What is a Chicken? A Look at the Bird We Love to Eat

Breeding increased under the Roman Empire and reduced in the Middle Ages. Middle Eastern chicken remains go back to a little earlier than 2000 BC in Syria. Chickens reached Egypt via the Middle East for purposes of cockfighting about 1400 BC and became widely bred in Egypt around 300 BC. Re-examination of bones from over 600 sites, and dating of those from 23 sites, identified the earliest probable chicken bones as from central Thailand, at Ban Non Wat, some 3,250 years ago. 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 sits on the nest, fluffing up or pecking defensively if disturbed.

Farmers have developed numerous breeds and varieties to fulfill commercial requirements. At about six months, males produce viable sperm, and females produce viable eggs. The time between ovulation and egg-laying is approximately 23–26 hours. Males (called cocks or roosters) and females (hens) are known for their fleshy combs, lobed wattles hanging below the bill, and high-arched tails.

Animal Names Glossary

• Learning about the different chicken classifications is vital for successful chicken farming.
• Chickens will sometimes attempt flight simply to explore their surroundings, however, they will especially fly in an attempt to flee when they perceive danger or pursued by a predator.
• The breed affects all the physical attributes of a chicken, from size to egg production, meat production, and feather quality.
• As with all birds, reproduction is controlled by a neuroendocrine system, the Gonadotropin-Releasing Hormone-I neurons in the hypothalamus.
• Breeders create various strains for specific purposes, such as egg and meat production.
• While the origin is Germanic, it is unclear exactly where the word came from, although it could ultimately have come from an imitation of the sound a chicken makes.

Equally important, embryologists can carry out experiments on such embryos, close the egg again and study the effects later in development. Chickens are social, inquisitive, intelligent birds, and many people find their behaviour entertaining. 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. 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. 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 are common and widespread domestic animals, with a total population of 23.7 billion as of 2018update.

Chicken breeds can either be egg or meat producers. Some hens, for instance, can lay around 150 eggs annually, while others can lay over 300 eggs. Adult female chickens lay a varied number of eggs annually. Modern egg-laying breeds rarely go broody and those that do often stop part-way through the incubation cycle. If the eggs are not fertilized and do not hatch, the hen will eventually grow tired of being broody and leave the nest. The hen can hear the chicks peeping inside the eggs, and will gently cluck to encourage them to break out of their shells.

Despite the chicken’s close relationship with the red jungle fowl, there is evidence that the gray jungle fowl (G. sonneratii) of southern India and other jungle fowl species, also members of Gallus, may have contributed to the bird’s ancestry. This stimulates the hen to lose her feathers but also re-invigorates egg-production. In some other countries, flocks are sometimes force-moulted rather than being slaughtered to re-invigorate egg-laying. After 12 months of laying, the commercial hen’s egg-laying ability declines to the point where the flock is commercially unviable. According to the Worldwatch Institute, 74% of the world’s poultry meat and 68% of eggs are produced this way.

It is estimated that chickens share between 71 and 79% of their genome with 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). Inbreeding of White Leghorn chickens tends to cause inbreeding depression expressed as reduced egg number and delayed sexual maturity. Wild junglefowl can fly, whereas domestic chickens and their flight muscles are too heavy to allow them to fly more than a short distance.

In situations where one adult bird challenges another—which happens jaya9betting.com/bonuses/ most often when a new bird is introduced into the flock—fights involving males risk injury and death more often than fights involving females. In groups of male chicks, however, fights for dominance may continue into adulthood. The pecking order is established within groups of female chicks by the 10th week of life. Chickens belonging to the same age cohort and sex are often kept together in industrial production settings.

Sometimes a hen will stop laying eggs to concentrate on the incubation of her eggs. When a rooster finds food he may call the other chickens to eat it first. Domestic chickens are typically fed commercially prepared feed that includes a protein source as well as grains. Chickens can be kept as pets, for breeding, egg laying and a food product.
