The gizzard , also referred to as the ventriculus , gastric mill , and gigerium , is an organ found in the digestive tract of some animals, including archosaurs ( birds and other dinosaurs , crocodiles , alligators , pterosaurs ), earthworms , some gastropods , some fish , and some crustaceans . This specialized stomach constructed of thick muscular walls is used for grinding up food, often aided by particles of stone or grit. In certain insects and molluscs , the gizzard features chitinous plates or teeth.

106-572: The word gizzard comes from the Middle English giser , which derives from a similar word in Old French gésier , which itself evolved from the Latin gigeria , meaning giblets . Birds swallow food and store it in their crop if necessary. Then the food passes into their glandular stomach, also called the proventriculus , which is also sometimes referred to as the true stomach. This

212-414: A predator is approaching from the air or on the ground. To initiate courting, some roosters may dance in a circle around or near a hen (a circle dance), often lowering the wing which is closest to the hen. The dance triggers a response in the hen and when she responds to his call, the rooster may mount the hen and proceed with the mating. Mating typically involves a sequence in which the male approaches

318-783: A Gizzard Fest each June since 2000; a gizzard-eating contest is among the weekend's events. In the Southern United States , the gizzard is typically served fried, sometimes eaten with hot sauce or honey mustard, or added to crawfish boil along with crawfish sauce , and it is also used in traditional New Orleans gumbo . In Mexico , they are eaten with rice or with chicken soup. They are also served grilled and prepared scrambled with eggs, onions, garlic and salsa; and served with beans and tortillas for breakfast and other meals. In Trinidad and Tobago , gizzards are curried and served with rice or roti bread; it can also be stewed. The term "gizzards" can also, by extension, refer to

424-738: A demonstrative ( þis , þat ), after a possessive pronoun (e.g., hir , our ), or with a name or in a form of address. This derives from the Old English "weak" declension of adjectives. This inflexion continued to be used in writing even after final -e had ceased to be pronounced. In earlier texts, multisyllable adjectives also receive a final -e in these situations, but this occurs less regularly in later Middle English texts. Otherwise, adjectives have no ending and adjectives already ending in -e etymologically receive no ending as well. Earlier texts sometimes inflect adjectives for case as well. Layamon's Brut inflects adjectives for

530-467: A few preferred locations, rather than having a different nest for every bird. Under natural conditions, most birds lay only until a clutch is complete; they then incubate all the eggs. This is called "going broody ". The hen sits on the nest, fluffing up or pecking defensively if disturbed. She rarely leaves the nest until the eggs have hatched. Eggs of chickens from the high-altitude region of Tibet have special physiological adaptations that result in

636-418: A green or yellowish membrane lining the inside, which must be peeled off before cooking, as it lends a very bitter taste to the food. In traditional Eastern European Jewish cuisine , the gizzards, necks and feet of chickens were often cooked together, although not the liver , which per kosher law must be broiled . Kosher butchers often sell roasting chickens with the gizzard, neck and feet butchered and left in

742-421: A higher hatching rate in low oxygen environments. When eggs are placed in a hypoxic environment, chicken embryos from these populations express much more hemoglobin than embryos from other chicken populations. This hemoglobin has a greater affinity for oxygen, binding oxygen more readily. Fertile chicken eggs hatch at the end of the incubation period, about 21 days; the chick uses its egg tooth to break out of

848-502: A largely Anglo-Saxon vocabulary (with many Norse borrowings in the northern parts of the country) but a greatly simplified inflectional system. The grammatical relations that were expressed in Old English by the dative and instrumental cases were replaced in Early Middle English with prepositional constructions. The Old English genitive - es survives in the -'s of the modern English possessive , but most of

954-494: A lengthened – and later also modified – pronunciation of a preceding vowel. For example, in name , originally pronounced as two syllables, the /a/ in the first syllable (originally an open syllable) lengthened, the final weak vowel was later dropped, and the remaining long vowel was modified in the Great Vowel Shift (for these sound changes, see Phonology , above). The final ⟨e⟩ , now silent, thus became

1060-495: A lesser extent), and, therefore, it cannot be attributed simply to the influence of French-speaking sections of the population: English did, after all, remain the vernacular . It is also argued that Norse immigrants to England had a great impact on the loss of inflectional endings in Middle English. One argument is that, although Norse and English speakers were somewhat comprehensible to each other due to similar morphology,

1166-593: A process called apophony ), as in Modern English. With the discontinuation of the Late West Saxon standard used for the writing of Old English in the period prior to the Norman Conquest, Middle English came to be written in a wide variety of scribal forms, reflecting different regional dialects and orthographic conventions. Later in the Middle English period, however, and particularly with

1272-651: A sacred rooster, often during a ritual cockfight , used as a form of communication with the gods. In Gabriel García Márquez 's Nobel-Prize-winning 1967 novel One Hundred Years Of Solitude , cockfighting is outlawed in the town of Macondo after the patriarch of the Buendia family murders his cockfighting rival and is haunted by the man's ghost. Chicken jokes have been made at least since The Knickerbocker published one in 1847. Chickens have been featured in art in farmyard scenes such as Adriaen van Utrecht 's 1646 Turkeys and Chickens and Walter Osborne 's 1885 Feeding

1378-427: A short distance. Size and coloration vary widely between breeds. Adult chickens of both sexes have a fleshy crest on their heads called a comb or cockscomb, and hanging flaps of skin on either side under their beaks called wattles ; combs and wattles are more prominent in males . Some breeds have a mutation that causes extra feathering under the face, giving the appearance of a beard. Chickens are omnivores . In

1484-401: A single domestication event of the red junglefowl in present-day Thailand gave rise to the modern chicken with minor transitions separating the modern breeds. The red junglefowl is well adapted to take advantage of the vast quantities of seed produced during the end of the multi-decade bamboo seeding cycle , to boost its own reproduction. In domesticating the chicken, humans took advantage of

1590-481: A street food in a skewered barbecue style, though some households treat it like an entree. The most common style is "Adobo". In Ghana and Togo , it is eaten boiled, fried or grilled. Grilled, skewered gizzards, with spices and optional green peppers and onions, are popular. In Nigeria , gizzard is either grilled or fried and served with stew and fried plantain , known as gizdodo . Skewered gizzards are also popular. In Kenya , Uganda , Cameroon and Nigeria ,

1696-521: A total population of 26.5 billion as of 2023 , and an annual production of more than 50 billion birds. A hen bred for laying can produce over 300 eggs per year. There are numerous cultural references to chickens in folklore, religion, and literature. Terms for chickens include: Chicken can mean a chick , as in William Shakespeare 's play Macbeth , where Macduff laments the death of "all my pretty chickens and their dam". The usage

1802-524: A variant of the Northumbrian dialect (prevalent in northern England and spoken in southeast Scotland ). During the Middle English period, many Old English grammatical features either became simplified or disappeared altogether. Noun, adjective, and verb inflections were simplified by the reduction (and eventual elimination) of most grammatical case distinctions. Middle English also saw considerable adoption of Anglo-Norman vocabulary, especially in

1908-564: A vector for bacterial diseases such as salmonellosis and spirochaetosis . Viral diseases include avian influenza . Chickens are common and widespread domestic animals, with a total population of 23.7 billion as of 2018 . More than 50 billion chickens are reared annually as a source of meat and eggs. In the United States alone, more than 8 billion chickens are slaughtered each year for meat, and more than 300 million chickens are reared for egg production. The vast majority of poultry

2014-617: Is a contest held in a ring called a cockpit between two cocks. Cockfighting is outlawed in many countries as involving cruelty to animals . The activity seems to have been practised in the Indus Valley civilisation from 2500 to 2100 BC. In the process of domestication, chickens were apparently kept initially for cockfighting, and only later used for food. Chickens have long been used as model organisms to study developing embryos. Large numbers of embryos can be provided commercially; fertilized eggs can easily be opened and used to observe

2120-477: Is a popular dish. In Iran , some kebab restaurants mix chicken gizzards in their koobideh kebabs to increase the meat content. Gizzards are usually cooked at the same time along with chicken, packets of gizzards are also sold separately. In Nepal , gizzard is called jaatey or pangra . It is eaten most often with drinks. In the Philippines , gizzard is called "Balun Balunan". It is usually cooked as

2226-550: Is famous for its brand of spicy gizzard, called jiujiuya (Simplified Chinese:久久鸭). In Northern China, one can find barbecued duck gizzard. The word sangdana is commonly used to refer to chicken gizzards in Northern India . The word is derived from Persian (sang = stone and dana = grain). Another name is pathri . It may be served cooked in a curry, while barbecued skewered gizzards are also popular. In Kerala , vattum-karulum (literally translates to gizzard-liver curry)

2332-592: Is inhumane towards sentient animals . Advocates of intensive farming say that their efficient systems save land and food resources owing to increased productivity, and that the animals are looked after in a controlled environment. Chickens farmed for meat are called broilers . Broiler breeds typically take less than six weeks to reach slaughter size, some weeks longer for free range and organic broilers. Chickens farmed primarily for eggs are called layer hens. The UK alone consumes more than 34 million eggs per day. Hens of some breeds can produce over 300 eggs per year;

2438-433: Is now rare and used only in oxen and as part of a double plural , in children and brethren . Some dialects still have forms such as eyen (for eyes ), shoon (for shoes ), hosen (for hose(s) ), kine (for cows ), and been (for bees ). Grammatical gender survived to a limited extent in early Middle English before being replaced by natural gender in the course of the Middle English period. Grammatical gender

2544-561: Is prepared raw and eaten mixed with garlic and onion. In Taiwan , gizzards are often slow-cooked and served hot or cold in slices, with green onions and soy sauce. Skewered deep-fried gizzards without batter are also popular and served on the menu of many fried chicken stores . In Mainland China , duck gizzard is a common snack, eaten alongside other duck parts such as feet, neck, heart, tongue, or head. Areas famous for their gizzard are Sichuan and Hubei provinces. Wuhan city in Hubei

2650-510: Is preserved in placenames such as the Hen and Chicken Islands . In older sources, and still often in trade and scientific contexts, chickens as a species are described as common fowl or domestic fowl . Chickens are relatively large birds , active by day . The body is round, the legs are unfeathered in most breeds, and the wings are short. Wild junglefowl can fly ; chickens and their flight muscles are too heavy to allow them to fly more than

2756-477: Is raised in factory farms . According to the Worldwatch Institute , 74% of the world's poultry meat and 68% of eggs are produced this way. An alternative to intensive poultry farming is free-range farming. Friction between these two main methods has led to long-term issues of ethical consumerism . Opponents of intensive farming argue that it harms the environment, creates human health risks and

2862-524: Is supplemented by mentions in historical texts from the last few centuries BC, and by depictions in prehistoric artworks, such as across Central Asia. Chickens were widespread throughout southern Central Asia by the 4th century BC. Middle Eastern chicken remains go back to a little earlier than 2000 BC in Syria . Phoenicians spread chickens along the Mediterranean coasts as far as Iberia. During

2968-428: Is the secretory part of the stomach. Then the food passes into the gizzard (also known as the muscular stomach or ventriculus ). The gizzard can grind the food with previously swallowed grit and pass it back to the true stomach, and vice versa. In layman's terms, the gizzard 'chews' the food for the bird because it does not have teeth to chew food the way humans and other mammals do. By comparison, although in birds

3074-464: Is thought that some extinct birds like Enantiornithes did not have gizzards. The mullet ( Mugilidae ) found in estuarine waters worldwide, and the gizzard or mud shad , found in freshwater lakes and streams from New York to Mexico, have gizzards. The gillaroo ( Salmo stomachius ), a richly colored species of trout found in Lough Melvin , a lake in the north of Ireland, has a gizzard which

3180-467: Is used to aid the digestion of water snails, the main component of its diet. Some crustaceans have a gizzard although this is usually referred to as a gastric mill. Earthworms also have gizzards. Poultry gizzards are a popular food throughout the world. Grilled chicken gizzards are sold as street food in Haiti and throughout Southeast Asia . They are considered offal . Giblets consist of

3286-553: The Arauco Peninsula in south-central Chile were radiocarbon dated as pre-Columbian, and DNA analysis suggested they were related to prehistoric populations in Polynesia. However, further study of the same bones cast doubt on the findings. Chicken remains have been difficult to date, given the small and fragile bird bones; this may account for discrepancies in dates given by different sources. Archaeological evidence

3392-524: The Augustinian canon Orrm wrote the Ormulum , one of the oldest surviving texts in Middle English. The influence of Old Norse aided the development of English from a synthetic language with relatively free word order to a more analytic language with a stricter word order. Both Old English and Old Norse were synthetic languages with complicated inflections. Communication between Vikings in

3498-597: The Danelaw and their Anglo-Saxon neighbours resulted in the erosion of inflection in both languages. Old Norse may have had a more profound impact on Middle and Modern English development than any other language. The effect of Old Norse on Old English was substantive, pervasive, and of a democratic character. Like close cousins, Old Norse and Old English resembled each other, and with some words and grammatical structures in common, speakers of each language roughly understood each other, but according to historian Simeon Potler

3604-523: The Dordogne region, duck gizzards are eaten in the traditional Périgordian salad, along with walnuts , croutons and lettuce . In Italy , gizzards are often used mixed with other offal . In eastern Slavic countries, gizzards are the basis of many soups, such as rassolnik . In Yiddish , gizzards are referred to as pupik'lech (also pipiklach, in its less normative form), literally meaning navels . The gizzards of kosher species of birds have

3710-616: The Early Modern English and Modern English eras. Middle English generally did not have silent letters . For example, knight was pronounced [ˈkniçt] (with both the ⟨k⟩ and the ⟨gh⟩ pronounced, the latter sounding as the ⟨ch⟩ in German Knecht ). The major exception was the silent ⟨e⟩ – originally pronounced but lost in normal speech by Chaucer's time. This letter, however, came to indicate

3816-623: The Gonadotropin-Releasing Hormone-I neurons in the hypothalamus . Reproductive hormones including estrogen , progesterone , and gonadotropins ( luteinizing hormone and follicle-stimulating hormone ) initiate and maintain sexual maturation changes. Reproduction declines with age, thought to be due to a decline in GnRH-I-N. Hens often try to lay in nests that already contain eggs and sometimes move eggs from neighbouring nests into their own. A flock thus uses only

3922-631: The Hellenistic period (4th–2nd centuries BC), in the southern Levant , chickens began to be widely domesticated for food. The first pictures of chickens in Europe are found on Corinthian pottery of the 7th century BC. Breeding increased under the Roman Empire and reduced in the Middle Ages . Genetic sequencing of chicken bones from archaeological sites in Europe revealed that in

4028-788: The High Middle Ages chickens became less aggressive and began to lay eggs earlier in the breeding season. Chickens reached Egypt via the Middle East for purposes of cockfighting about 1400 BC and became widely bred in Egypt around 300 BC. Three possible routes of introduction into Africa around the early first millennium AD could have been through the Egyptian Nile Valley, the East Africa Roman-Greek or Indian trade, or from Carthage and

In the aftermath of the Black Death of the 14th century, there was significant migration into London , of people to the counties of the southeast of England and from the east and central Midlands of England, and a new prestige London dialect began to develop as a result of this clash of

4664-663: The 1540s after the printing and wide distribution of the English Bible and Prayer Book , which made the new standard of English publicly recognizable and lasted until about 1650. The main changes between the Old English sound system and that of Middle English include: The combination of the last three processes listed above led to the spelling conventions associated with silent ⟨e⟩ and doubled consonants (see under Orthography , below). Middle English retains only two distinct noun-ending patterns from

4770-618: The Americas before Western contact is debated by researchers, but blue-egged chickens, found only in the Americas and Asia, suggest an Asian origin for early American chickens. A lack of data from Thailand, Russia, the Indian subcontinent, Southeast Asia and Sub-Saharan Africa makes it difficult to lay out a clear map of the spread of chickens in these areas; better description and genetic analysis of local breeds threatened by extinction may also help with research into this area. Chicken bones from

Chickens are susceptible both to parasites such as mites , and to diseases caused by pathogens such as bacteria and viruses . The parasite Dermanyssus gallinae feeds on blood, causing irritation and reducing egg production, and acts as

4982-572: The Church and legalities, which used Latin and Law French respectively. The Chancery Standard's influence on later forms of written English is disputed, but it did undoubtedly provide the core around which Early Modern English formed. Early Modern English emerged with the help of William Caxton 's printing press, developed during the 1470s. The press stabilized English through a push towards standardization, led by Chancery Standard enthusiast and writer Richard Pynson . Early Modern English began in

This longer time frame would extend the corpus to include many Middle English Romances (especially those of the Auchinleck manuscript c.  1330 ). Gradually, the wealthy and the government Anglicised again, although Norman (and subsequently French ) remained the dominant language of literature and law until

5194-591: The Norse speakers' inability to reproduce the ending sounds of English words influenced Middle English's loss of inflectional endings. Important texts for the reconstruction of the evolution of Middle English out of Old English are the Peterborough Chronicle , which continued to be compiled up to 1154; the Ormulum , a biblical commentary probably composed in Lincolnshire in the second half of

5300-544: The Old English -eþ , Midland dialects showing -en from about 1200, and Northern forms using -es in the third person singular as well as the plural. The past tense of weak verbs was formed by adding an -ed(e) , -d(e) , or -t(e) ending. The past-tense forms, without their personal endings, also served as past participles with past-participle prefixes derived from Old English: i- , y- , and sometimes bi- . Strong verbs , by contrast, formed their past tense by changing their stem vowel (e.g., binden became bound ,

In some other countries, flocks are sometimes force moulted rather than being slaughtered to re-invigorate egg-laying. This involves complete withdrawal of food (and sometimes water) for 7–14 days or sufficiently long to cause a body weight loss of 25 to 35%, or up to 28 days under experimental conditions. This stimulates

5618-710: The abundance of Modern English words for the mechanisms of government that are derived from Anglo-Norman, such as court , judge , jury , appeal , and parliament . There are also many Norman-derived terms relating to the chivalric cultures that arose in the 12th century, an era of feudalism , seigneurialism , and crusading . Words were often taken from Latin, usually through French transmission. This gave rise to various synonyms, including kingly (inherited from Old English), royal (from French, inherited from Vulgar Latin), and regal (from French, which borrowed it from Classical Latin). Later French appropriations were derived from standard, rather than Norman, French. Examples of

5724-494: The areas of politics, law, the arts, and religion, as well as poetic and emotive diction. Conventional English vocabulary remained primarily Germanic in its sources, with Old Norse influences becoming more apparent. Significant changes in pronunciation took place, particularly involving long vowels and diphthongs, which in the later Middle English period began to undergo the Great Vowel Shift . Little survives of early Middle English literature , due in part to Norman domination and

5830-638: The beginning of the 13th century, this delay in Scandinavian lexical influence in English has been attributed to the lack of written evidence from the areas of Danish control, as the majority of written sources from Old English were produced in the West Saxon dialect spoken in Wessex , the heart of Anglo-Saxon political power at the time. The Norman Conquest of England in 1066 saw the replacement of

In Japan , gizzard is called zuri or sunagimo ; usually it is cooked in yakitori (Japanese style skewered barbecue). In Kyushu (southern Japan), gizzard is fried into karaage . In Korea , chicken gizzard, called dak-ttongjip , is stir-fried and eaten as anju or yasik . In some places, it

The final gene set contained 26,640 genes (including noncoding genes and pseudogenes ), with a total of 19,119 protein-coding genes, a similar number to the human genome. In 2006, scientists researching the ancestry of birds switched on a chicken recessive gene , talpid2 , and found that

The role of Anglo-Norman as the language of government and law can be seen in

6254-507: The comparative and superlative (e.g., greet , great; gretter , greater). Adjectives ending in -ly or -lich formed comparatives either with -lier , -liest or -loker , -lokest . A few adjectives also displayed Germanic umlaut in their comparatives and superlatives, such as long , lenger . Other irregular forms were mostly the same as in modern English. Middle English personal pronouns were mostly developed from those of Old English , with

At least some pterosaurs seemingly had gizzards. The most notable cases are Pterodaustro (inferred via gastroliths) and Rhamphorhynchus (directly preserved). Conversely, it

6784-531: The double consonant represented a sound that was (or had previously been) geminated (i.e., had genuinely been "doubled" and would thus have regularly blocked the lengthening of the preceding vowel). In other cases, by analogy, the consonant was written double merely to indicate the lack of lengthening. The basic Old English Latin alphabet consisted of 20 standard letters plus four additional letters: ash ⟨æ⟩ , eth ⟨ð⟩ , thorn ⟨þ⟩ , and wynn ⟨ƿ⟩ . There

This involves the sacrifice of

6996-468: The end of the Middle English period only the strong -'s ending (variously spelled) was in use. Some formerly feminine nouns, as well as some weak nouns, continued to make their genitive forms with -e or no ending (e.g., fole hoves , horses' hooves), and nouns of relationship ending in -er frequently have no genitive ending (e.g., fader bone , "father's bane"). The strong -(e)s plural form has survived into Modern English. The weak -(e)n form

7844-507: The heart, liver and gizzard of a bird, and are often eaten themselves or used as the basis for a soup or stock. Gizzard and mashed potato is a popular dish in many European countries. Stewed gizzards are eaten as a snack in Portugal , with a tomato based sauce. In Spain , they are cooked on the plancha , and eaten while they are crispy on the outside. In Hungary , it is made with paprika as zúza pörkölt . In France , especially

7950-952: The hen to lose her feathers but also re-invigorates egg-production. Some flocks may be force-moulted several times. In 2003, more than 75% of all flocks were moulted in the US. Keeping chickens as pets became increasingly popular in the 2000s among urban and suburban residents. Many people obtain chickens for their egg production but often name them and treat them as any other pet like cats or dogs. Chickens provide companionship and have individual personalities. While many do not cuddle much, they will eat from one's hand, jump onto one's lap, respond to and follow their handlers, as well as show affection. Chickens are social, inquisitive, intelligent birds, and many people find their behaviour entertaining. Certain breeds, such as silkies and many bantam varieties, are generally docile and are often recommended as good pets around children with disabilities. A cockfight

8056-418: The highest authenticated rate of egg laying is 371 eggs in 364 days. After 12 months of laying, the commercial hen's egg-laying ability declines to the point where the flock is commercially unviable. Hens, particularly from battery cage systems, are sometimes infirm or have lost a significant amount of their feathers, and their life expectancy has been reduced from around seven years to less than two years. In

8162-412: The indicator of the longer and changed pronunciation of ⟨a⟩ . In fact, vowels could have this lengthened and modified pronunciation in various positions, particularly before a single consonant letter and another vowel or before certain pairs of consonants. A related convention involved the doubling of consonant letters to show that the preceding vowel was not to be lengthened. In some cases,

8268-561: The main difference lied on their inflectional endings, which led to much confusion within the mixed population that existed in the Danelaw, this endings tended gradually to become obscured and finally lost, "simplifying English grammar" in the process. In time, the inflections melted away and the analytic pattern emerged. Viking influence on Old English is most apparent in pronouns , modals, comparatives, pronominal adverbs (like hence and together ), conjunctions, and prepositions show

8374-417: The masculine accusative, genitive, and dative, the feminine dative, and the plural genitive. The Owl and the Nightingale adds a final -e to all adjectives not in the nominative, here only inflecting adjectives in the weak declension (as described above). Comparatives and superlatives were usually formed by adding -er and -est . Adjectives with long vowels sometimes shortened these vowels in

8480-427: The more complex system of inflection in Old English : Nouns of the weak declension are primarily inherited from Old English n -stem nouns but also from ō -stem, wō -stem, and u -stem nouns, which did not inflect in the same way as n -stem nouns in Old English, but joined the weak declension in Middle English. Nouns of the strong declension are inherited from the other Old English noun stem classes. Some nouns of

8586-490: The most marked Danish influence. The best evidence of Scandinavian influence appears in extensive word borrowings; however, texts from the period in Scandinavia and Northern England do not provide certain evidence of an influence on syntax. However, at least one scholarly study of this influence shows that Old English may have been replaced entirely by Norse, by virtue of the change from Old English to Norse syntax. While

8692-551: The most part, being improvised. By the end of the period (about 1470), and aided by the invention of the printing press by Johannes Gutenberg in 1439, a standard based on the London dialects (Chancery Standard) had become established. This largely formed the basis for Modern English spelling, although pronunciation has changed considerably since that time. Middle English was succeeded in England by Early Modern English , which lasted until about 1650. Scots developed concurrently from

8798-537: The most popular commercial breed shows that the White Leghorn breed possesses a mosaic of divergent ancestries inherited from subspecies of red junglefowl. A word for the domestic chicken ( *manuk ) is part of the reconstructed Proto-Austronesian language , indicating they were domesticated by the Austronesian peoples since ancient times. Chickens, together with dogs and pigs, were carried throughout

8904-693: The old insular g and the Carolingian g (modern g ), the former continued in use as a separate letter, known as yogh , written ⟨ȝ⟩ . This was adopted for use to represent a variety of sounds: [ɣ], [j], [dʒ], [x], [ç] , while the Carolingian g was normally used for [g]. Instances of yogh were eventually replaced by ⟨j⟩ or ⟨y⟩ and by ⟨gh⟩ in words like night and laugh . In Middle Scots , yogh became indistinguishable from cursive z , and printers tended to use ⟨z⟩ when yogh

9010-423: The other case endings disappeared in the Early Middle English period, including most of the roughly one dozen forms of the definite article ("the"). The dual personal pronouns (denoting exactly two) also disappeared from English during this period. The loss of case endings was part of a general trend from inflections to fixed word order that also occurred in other Germanic languages (though more slowly and to

9116-624: The period when Middle English was spoken as being from 1150 to 1500. This stage of the development of the English language roughly coincided with the High and Late Middle Ages . Middle English saw significant changes to its vocabulary, grammar, pronunciation, and orthography . Writing conventions during the Middle English period varied widely. Examples of writing from this period that have survived show extensive regional variation. The more standardized Old English literary variety broke down and writing in English became fragmented and localized and was, for

9222-463: The polishing action in the animal's stomach. When too smooth to do their required work, they may be excreted or regurgitated. Pangolins lack teeth and grind their food in a gizzard-like structure. All birds have gizzards. The gizzards of emus , turkeys , chickens , and ducks are most notable in cuisine (see below). Crocodilians such as alligators and crocodiles also have gizzards. Dinosaurs that are believed to have had gizzards based on

9328-403: The prestige that came with writing in French rather than English. During the 14th century, a new style of literature emerged with the works of writers including John Wycliffe and Geoffrey Chaucer , whose Canterbury Tales remains the most studied and read work of the period. The transition from Late Old English to Early Middle English had taken place by the 1150s to 1180s, the period when

9434-609: The red junglefowl's ability to reproduce prolifically when exposed to a surge in its food supply. Exactly when and where the chicken was domesticated remains controversial. Genomic studies estimate that the chicken was domesticated 8,000 years ago in Southeast Asia and spread to China and India 2,000 to 3,000 years later. Archaeological evidence supports domestic chickens in Southeast Asia well before 6000 BC, China by 6000 BC and India by 2000 BC. A landmark 2020 Nature study that fully sequenced 863 chickens across

9540-569: The resulting doublet pairs include warden (from Norman) and guardian (from later French; both share a common ancestor loaned from Germanic). The end of Anglo-Saxon rule did not result in immediate changes to the language. The general population would have spoken the same dialects as they had before the Conquest. Once the writing of Old English came to an end, Middle English had no standard language, only dialects that evolved individually from Old English. Early Middle English (1150–1350) has

9646-462: The same species. Domesticated chickens freely interbreed with populations of red junglefowl. The domestic chicken has subsequently hybridised with grey junglefowl , Sri Lankan junglefowl and green junglefowl ; a gene for yellow skin, for instance, was incorporated into domestic birds from the grey junglefowl ( G. sonneratii ). It is estimated that chickens share between 71 and 79% of their genome with red junglefowl. According to one early study,

9752-807: The second half of the 14th century in the emerging London dialect, although he also portrays some of his characters as speaking in northern dialects, as in " The Reeve's Tale ". In the English-speaking areas of lowland Scotland , an independent standard was developing, based on the Northumbrian dialect . This would develop into what came to be known as the Scots language . A large number of terms for abstract concepts were adopted directly from scholastic philosophical Latin (rather than via French). Examples are "absolute", "act", "demonstration", and "probable". The Chancery Standard of written English emerged c.  1430 in official documents that, since

9858-458: The second person singular in -(e)st (e.g., þou spekest , "thou speakest"), and the third person singular in -eþ (e.g., he comeþ , "he cometh/he comes"). ( þ (the letter "thorn") is pronounced like the unvoiced th in "think", but under certain circumstances, it may be like the voiced th in "that"). The following table illustrates a typical conjugation pattern: Plural forms vary strongly by dialect, with Southern dialects preserving

9964-703: The shell. Hens remain on the nest for about two days after the first chick hatches; during this time the newly hatched chicks feed by absorbing the internal yolk sac . The hen guards her chicks and broods them to keep them warm. She leads them to food and water and calls them towards food. The chicks imprint on the hen and subsequently follow her continually. She continues to care for them until they are several weeks old. Inbreeding of White Leghorn chickens tends to cause inbreeding depression expressed as reduced egg number and delayed sexual maturity. Strongly inbred Langshan chickens display obvious inbreeding depression in reproduction, particularly for traits such as age when

10070-443: The stomach occurs in the digestive tract prior to the gizzard, in grasshoppers the gizzard occurs prior to the stomach, while in earthworms there is only a gizzard, and no stomach. In order to protect the muscles of the gizzard, the organ has a multi-layered membrane - or gastric cuticle - made of koilin, a carbohydrate-protein complex (and not keratin as once believed) to protect the muscles. The thickness of this membrane varies with

10176-409: The strong type have an -e in the nominative/accusative singular, like the weak declension, but otherwise strong endings. Often, these are the same nouns that had an -e in the nominative/accusative singular of Old English (they, in turn, were inherited from Proto-Germanic ja -stem and i -stem nouns). The distinct dative case was lost in early Middle English, and although the genitive survived, by

10282-440: The top levels of the English-speaking political and ecclesiastical hierarchies by Norman rulers who spoke a dialect of Old French , now known as Old Norman , which developed in England into Anglo-Norman . The use of Norman as the preferred language of literature and polite discourse fundamentally altered the role of Old English in education and administration, even though many Normans of this period were illiterate and depended on

10388-537: The types of food the animal eats, with diets heavier in grains, seeds, and insects creating thicker membranes than those consisting of fruits, worms, meat, and other softer edibles. In some animals the membrane is slowly worn and replaced over time, while others will discard the worn lining in its entirety periodically. The lining is critical to the proper functioning of the gizzard, but in some animals it can play an additional role as well. The male hornbill , for example, will fill its gizzard with fruit and then slough off

10494-530: The wild, they scratch at the soil to search for seeds, insects, and animals as large as lizards , small snakes, and young mice . A chicken may live for 5–10 years, depending on the breed . The world's oldest known chicken lived for 16 years. Chickens are gregarious , living in flocks , and incubate eggs and raise young communally. Individual chickens dominate others, establishing a pecking order ; dominant individuals take priority for access to food and nest sites. The concept of dominance, involving pecking,

10600-404: The world suggests that all domestic chickens originate from a single domestication event of red junglefowl whose present-day distribution is predominantly in southwestern China, northern Thailand and Myanmar. These domesticated chickens spread across Southeast and South Asia where they interbred with local wild species of junglefowl, forming genetically and geographically distinct groups. Analysis of

10706-553: Was described in female chickens by Thorleif Schjelderup-Ebbe in 1921 as the "pecking order". Male chickens tend to leap and use their claws in conflicts. Chickens are capable of mobbing and killing a weak or inexperienced predator, such as a young fox. A male's crowing is a loud and sometimes shrill call, serving as a territorial signal to other males, and in response to sudden disturbances within their surroundings. Hens cluck loudly after laying an egg and to call their chicks. Chickens give different warning calls to indicate that

10812-425: Was indicated by agreement of articles and pronouns (e.g., þo ule "the feminine owl") or using the pronoun he to refer to masculine nouns such as helm ("helmet"), or phrases such as scaft stærcne (strong shaft), with the masculine accusative adjective ending -ne . Single-syllable adjectives added -e when modifying a noun in the plural and when used after the definite article ( þe ), after

10918-649: Was not available in their fonts; this led to new spellings (often giving rise to new pronunciations), as in McKenzie , where the ⟨z⟩ replaced a yogh, which had the pronunciation /j/ . Chicken Gallus domesticus L. The chicken ( Gallus domesticus ) is a large and round short-winged bird , domesticated from the red junglefowl of Southeast Asia around 8,000 years ago. Most chickens are raised for food, providing meat and eggs ; others are kept as pets or for cockfighting . Chickens are common and widespread domestic animals, with

11024-520: Was not yet a distinct j , v , or w , and Old English scribes did not generally use k , q , or z . Ash was no longer required in Middle English, as the Old English vowel /æ/ that it represented had merged into /a/ . The symbol nonetheless came to be used as a ligature for the digraph ⟨ae⟩ in many words of Greek or Latin origin, as did ⟨œ⟩ for ⟨oe⟩ . Eth and thorn both represented /θ/ or its allophone / ð / in Old English. Eth fell out of use during

11130-417: Was ousted by it in most dialects by the 15th. The following table shows some of the various Middle English pronouns. Many other variations are noted in Middle English sources because of differences in spellings and pronunciations at different times and in different dialects. As a general rule, the indicative first person singular of verbs in the present tense ended in -e (e.g., ich here , "I hear"),

11236-475: Was some inflectional simplification (the distinct Old English dual forms were lost), but pronouns, unlike nouns, retained distinct nominative and accusative forms. Third person pronouns also retained a distinction between accusative and dative forms, but that was gradually lost: The masculine hine was replaced by him south of the River Thames by the early 14th century, and the neuter dative him
