The chicken 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.
Debeaking, beak trimming, or beak conditioning is the partial removal of the beak of poultry, especially layer hens and turkeys although it may also be performed on quail and ducks. Most commonly, the beak is shortened permanently, although regrowth can occur. The trimmed lower beak is somewhat longer than the upper beak. A similar but separate practice, usually performed by an avian veterinarian or an experienced birdkeeper, involves clipping, filing or sanding the beaks of captive birds for health purposes – in order to correct or temporarily to alleviate overgrowths or deformities and better allow the bird to go about its normal feeding and preening activities. Amongst raptor-keepers, this practice is commonly known as "coping".
A hatchery is a facility where eggs are hatched under artificial conditions, especially those of fish, poultry or even turtles. It may be used for ex situ conservation purposes, i.e. to breed rare or endangered species under controlled conditions; alternatively, it may be for economic reasons.
Free-range eggs are eggs produced from birds that may be permitted outdoors. The term "free-range" may be used differently depending on the country and the relevant laws, and is not regulated in many areas.
Free 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.
Forced molting, sometimes known as induced molting, is the practice by some poultry industries of artificially provoking a flock to molt simultaneously, typically by withdrawing food for 7–14 days and sometimes also withdrawing water for an extended period. Forced molting is usually implemented when egg-production is naturally decreasing toward the end of the first egg-laying phase. During the forced molt, the birds cease producing eggs for at least two weeks, which allows the bird's reproductive tracts to regress and rejuvenate. After the molt, the hen's egg production rate usually peaks slightly lower than the previous peak, but egg quality is improved. The purpose of forced molting is therefore to increase egg production, egg quality, and profitability of flocks in their second or subsequent laying phases, by not allowing the hen's body the necessary time to rejuvenate during the natural cycle of feather replenishment.
Chick culling or unwanted chick killing is the process of separating and killing unwanted chicks for which the intensive animal farming industry has no use. It occurs in all industrialised egg production, whether free range, organic, or battery cage. However, some certified pasture-raised egg farms are taking steps to eliminate the practice entirely. Worldwide, around 7 billion male chicks are culled each year in the egg industry. Because male chickens do not lay eggs and only those in breeding programmes are required to fertilise eggs, they are considered redundant to the egg-laying industry and are usually killed shortly after being sexed, which occurs just days after they are conceived or after they hatch. Some methods of culling that do not involve anaesthetics include: cervical dislocation, asphyxiation by carbon dioxide, and maceration using a high-speed grinder. Maceration is the primary method in the United States. Maceration is often a preferred method over carbon dioxide asphyxiation in western countries as it is often considered as "more humane" due to the deaths occurring immediately or within a second.
Battery cages are a housing system used for various animal production methods, but primarily for egg-laying hens. The name arises from the arrangement of rows and columns of identical cages connected, in a unit, as in an artillery battery. Although the term is usually applied to poultry farming, similar cage systems are used for other animals. Battery cages have generated controversy between advocates for animal welfare and industrial producers.
Intensive animal farming, industrial livestock production, and macro-farms, also known as factory farming, is a type of intensive agriculture, specifically an approach to animal husbandry designed to maximize production while minimizing costs. To achieve this, agribusinesses keep livestock such as cattle, poultry, and fish at high stocking densities, at large scale, and using modern machinery, biotechnology, and global trade. The main products of this industry are meat, milk and eggs for human consumption. There are issues regarding whether intensive animal farming is sustainable in the social long-run given its costs in resources. Analysts also raise issues about its ethics.
In poultry keeping, yarding is the practice of providing the poultry with a fenced yard in addition to a poultry house. Movable yarding is a form of managed intensive grazing.
Poultry 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.
The British Hen Welfare Trust (formerly the Battery Hen Welfare Trust) is the United Kingdom's first registered charity solely for laying hens. It was founded in April 2005 by Jane Howorth, and was established in order to raise awareness of the 20 million hens kept in cages in the UK at that time. Its activities include collecting hens which have reached the end of their commercial lives and re-homing them as pets. The charity's headquarters are near Rose Ash, North Devon.
Proposition 2 was a California ballot proposition in that state's general election on November 4, 2008. It passed with 63% of the votes in favor and 37% against. Submitted to the Secretary of State as the Prevention of Farm Animal Cruelty Act, the initiative's name was amended to officially be known as the Standards for Confining Farm Animals initiative. The official title of the statute enacted by the proposition is the Prevention of Farm Animal Cruelty Act.
Poultry farming is a part of the United States's agricultural economy.
Keeping chickens as pets, for eggs, meat, or for eating pests is popular in urban and suburban areas. Some people sell the eggs for side income.
Cannibalism 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. Cannibalism can occur as a consequence of feather pecking which has caused denuded areas and bleeding on a bird's skin. Cannibalism can cause large mortality rates within the flock and large decreases in production due to the stress it causes. Vent pecking, sometimes called 'cloacal cannibalism', is considered to be a separate form of cannibalistic pecking as this occurs in well-feathered birds and only the cloaca is targeted. There are several causes that can lead to cannibalism such as: light and overheating, crowd size, nutrition, injury/death, genetics and learned behaviour. Research has been conducted to attempt to understand why poultry engage in this behaviour, as it is not totally understood. There are known methods of control to reduce cannibalism such as crowd size control, beak trimming, light manipulation, perches, selective genetics and eyewear.
The broiler industry is the process by which broiler chickens are reared and prepared for meat consumption. Worldwide, in 2005 production was 71,851,000 tonnes. From 1985 to 2005, the broiler industry grew by 158%.
Animal welfare and rights in Denmark relates to the treatment of and laws concerning non-human animals in Denmark. Denmark has moderately strong protections for animals by international standards. In 2014 and again in 2020, Denmark received a B grade on the A–G scale of the World Animal Protection's Animal Protection Index.
In poultry farming, in-ovo sexing is a chick sexing method carried out while chicks are still in ovo. There are various methods to determine a chick's sex in the 21-day incubation period before it hatches.
Altsteirer, also known as the Styrian Hen and Chicken, Slovene: Štajerska kokoš or Štajerka, German: Altsteirer Huhn, is an autochthonous breed of domestic chicken originating in Slovenia and Austrian state Styria. The Styrian Hen is known as the only autochthonous (native) chicken breed of Slovenian area, with all other breeds being traditional at most, hence introduced in the past and consequently adapted to country's conditions. The Altsteirer's set of traits suggests the breed may share a common descent with other Mediterranean chicken breeds.
