[33], Traditionally, a flock of broilers consist of about 20,000 birds in a growout house that measures 400/500 feet long and 40/50 feet wide, thus providing about eight-tenths of a square foot per bird. In practicing poultry farming business, consideration should be made for the planning stage: Meat chickens, commonly called broilers, are floor-raised on litter such as wood shavings, peanut shells, and rice hulls, indoors in climate-controlled housing. [71], There is also a risk that crowded conditions in chicken farms will allow avian influenza (bird flu) to spread quickly. The birds are released daily from hutches or coops. [53], Beak-trimmed chicks initially peck less than non-trimmed chickens, which animal behavioralist Temple Grandin attributes to guarding against pain. Although the enriched housing system has its advantages such as reduced aggression towards one another and cleaner eggs, modern egg laying breeds often suffer from osteoporosis which results in the chicken's skeletal system being weakened. well-suited to become a poultry farmer or another similar career! Chickens: Layer Housing, Michael C. Appleby, Encyclopedia of Animal Science. [42][43][44][45][46][47] Severe beak trimming, or beak trimming birds at an older age, may cause chronic pain. In the case of no ventilation due to power failure during a heat wave, 20,000 chicken can die in a short period of time. Before 1950, this was contained largely by not eviscerating the carcass at the time of butchering, deferring this until the time of retail sale or in the home. In response to these bans, development of prototype commercial furnished cage systems began in the 1980s. [80] Incineration offers a swifter disposal method, but uses fuel energy and thus brings varying costs. In the United States, the national organization overseeing poultry production is the Food and Drug Administration (FDA). This compares with 41% being free range in 2009. After the marketing of birds the farmer must clean out and prepare for another flock. Breeder. The U.S. Food and Drug Administration (FDA), however, is the organization responsible for the regulation of foods in America, and all samples tested were "far less than the... amount allowed in a food product. A poultry farmer is someone who raises domesticated birds such as geese, ducks, turkeys or chickens for the purpose of farming meat or eggs for sale and consumption. You don’t want to waste your It has originated from the agricultural era. These houses are equipped with mechanical systems to deliver feed and water to the birds. The distinction is that free-range poultry are either totally unfenced, or the fence is so distant that it has little influence on their freedom of movement. [38], Conditions in chicken farms may be unsanitary, allowing the proliferation of bacteria such as Salmonella, E. coli and Campylobacter. Beak trimming in poultry. [37] They have a larger space allowance outside (at least 2 square metres and sometimes up to 10 square metres per bird). Meat inspector. Eggs are often laid on the ground or under cages in the aviary housing, causing workers to come close to the floor and force dust and bacteria into the air, which they then inhale during egg collection. [30] This is a result of the increased activity in the hens from the additional space and enrichment provided in the furnished housing system. In the UK, the Department for Environment, Food and Rural Affairs (Defra) states that a free-range chicken must have day-time access to open-air runs during at least half of its life. Enrichment of laying hen cages ultimately results in better bone quality. Battery cages are arranged in long rows as multiple tiers, often with cages back-to-back (hence the term). Environmental conditions are often automatically controlled in egg-laying systems. Scientific studies have shown that beak trimming is likely to cause both acute and chronic pain. [73] Two kilograms of grain must be fed to poultry to produce 1 kg of weight gain,[74] much less than that required for pork or beef. [33][34], In intensive broiler sheds, the air can become highly polluted with ammonia from the droppings. During egg production, large amounts of calcium are transferred from bones to create egg-shell. Benefits of battery cages include easier care for the birds, floor-laid eggs (which are expensive to collect) are eliminated, eggs are cleaner, capture at the end of lay is expedited, generally less feed is required to produce eggs, broodiness is eliminated, more hens may be housed in a given house floor space, internal parasites are more easily treated, and labor requirements are generally much reduced. More humane methods that could be used are low atmospheric pressure stunning and inert gas asphyxiation. In a good grow out a farmer should sell between 92 and 96 percent of their flock.

Defra figures indicate that 45% of eggs produced in the UK throughout 2010 were free range, 5% were produced in barn systems and 50% from cages. In the first week of a broiler's life, it can grow up to 300 percent of its body size. Enrichment such as nest boxes, perches, and dust baths are also provided so that the birds may carry out their natural behaviors such as nesting, roosting, and scratching as though they were outdoors.
