Feather peckingFeather pecking is a behavioural problem that occurs most frequently amongst domestic hens reared for egg production, although it does occur in other poultry such as pheasants, turkeys, ducks, broiler chickens and is sometimes seen in farmed ostriches. Feather pecking occurs when one bird repeatedly pecks at the feathers of another. The levels of severity may be recognized as mild and severe. Gentle feather pecking is considered to be a normal investigatory behaviour where the feathers of the recipient are hardly disturbed and therefore does not represent a problem.
Poultry farmingPoultry farming is the form of animal husbandry which raises domesticated birds such as chickens, ducks, turkeys and geese to produce meat or eggs for food. Poultry – mostly chickens – are farmed in great numbers. More than 60 billion chickens are killed for consumption annually. Chickens raised for eggs are known as layers, while chickens raised for meat are called broilers. In the United States, the national organization overseeing poultry production is the Food and Drug Administration (FDA).
Gallus gallus domesticusGallus gallus domesticus, en français la Poule domestique (femelle), le coq domestique (mâle), est une sous-espèce de l'ordre des Galliformes. Cet oiseau, principalement issu de la domestication du Coq doré sauvage, est élevé à la fois pour sa chair, pour ses œufs, pour le combat, pour le chant, parfois pour ses plumes et plus rarement encore pour sa crête ou pour des utilisations rituelles. De nombreuses races issues de la sélection opérée par les paysans au fil des siècles ont disparu.
Free rangeFree range denotes a method of farming husbandry where the animals, for at least part of the day, can roam freely outdoors, rather than being confined in an enclosure for 24 hours each day. On many farms, the outdoors ranging area is fenced, thereby technically making this an enclosure, however, free range systems usually offer the opportunity for the extensive locomotion and sunlight that is otherwise prevented by indoor housing systems. Free range may apply to meat, eggs or dairy farming.
BecUn bec, au sens strict, est une structure anatomique externe qui permet la prise alimentaire et donc la nutrition chez les oiseaux. Mais il permet aussi la toilette de l'animal, la nutrition des jeunes, la chasse d'une proie, la manipulation d'objets, et peut aussi être un élément important pour la parade nuptiale. La rhamphothèque est le tégument corné du bec recouvrant les deux mandibules osseuses. Le bec est plus précisément un phanère, au même titre que les plumes et les écailles, qui sont donc des productions cornées du tégument.
Domestic turkeyThe domestic turkey (Meleagris gallopavo domesticus) is a large fowl, one of the two species in the genus Meleagris and the same species as the wild turkey. Although turkey domestication was thought to have occurred in central Mesoamerica at least 2,000 years ago, recent research suggests a possible second domestication event in the area that is now the southwestern United States between 200 BC and AD 500. However, all of the main domestic turkey varieties today descend from the turkey raised in central Mexico that was subsequently imported into Europe by the Spanish in the 16th century.
Cannibalism in poultryCannibalism in poultry is the act of one individual of a poultry species consuming all or part of another individual of the same species as food. It commonly occurs in flocks of domestic hens reared for egg production, although it can also occur in domestic turkeys, pheasants and other poultry species. Poultry create a social order of dominance known as pecking order. When pressure occurs within the flock, pecking can increase in aggression and escalate to cannibalism.
Vent peckingVent pecking is an abnormal behaviour of birds performed primarily by commercial egg-laying hens. It is characterised by pecking damage to the cloaca, the surrounding skin and underlying tissue. Vent pecking frequently occurs immediately after an egg has been laid when the cloaca often remains partly everted exposing the mucosa, red from the physical trauma of oviposition or bleeding if the tissue is torn by her laying an egg. Vent pecking clearly causes pain and distress to the bird being pecked.
VolailleUne volaille est un oiseau domestique, appartenant généralement aux gallinacés ou aux palmipèdes, élevé pour sa chair, ses œufs, ses plumes. L'échelle d'élevage des volailles va de l'intensif industriel spécialisé pouvant regrouper des centaines de milliers d'individu à l'élevage paysan, fermier ou familial des quelques oiseaux rustiques. Il faut noter qu'en cuisine le lapin est considéré comme une volaille. thumb|Volailles d'un poulailler traditionnel européen (en coexistence avec les pigeons).
Poulet de chairUn poulet de chair, appelé aussi poulet à frire ou poulet à griller (broiler en anglais), est une Poule domestique (Gallus gallus domesticus) élevée spécifiquement pour la production de viande. Il possède des caractéristiques physiques différentes des poules pondeuses, des poules d'ornement ou des poules de compagnie.
