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

A flock thus uses only a few preferred locations, rather than having a different nest for every bird. Reproduction declines with age, thought to be due to a decline in GnRH-I-N. 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. 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.

Some meat-producing breeds include Jersey Giant, Buff Orpington, Cochin, and Malay. 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.

• Specialized breeds such as broilers and laying hens have been developed for meat and egg production, respectively.
• Breeding increased under the Roman Empire and reduced in the Middle Ages.
• The life span of a chicken varies between 5 – 7 years although there have been cases of chickens living 20 years or so.
• Sometimes a hen will stop laying eggs to concentrate on the incubation of her eggs.
• These birds also have different feather coloration, ranging from brown, white, gray, and black.

Specialized breeds such as broilers and laying hens have been developed for meat and egg production, respectively. Females (mature hens and younger chickens, called pullets) are raised for meat and for their edible eggs. In domesticating the chicken, humans took advantage of the red junglefowl’s ability to reproduce prolifically when exposed to a surge in its food supply. Strongly inbred Langshan chickens display obvious inbreeding depression in reproduction, particularly for traits such as age when the first egg is laid and egg number.

A chicken’s physical characteristics differ by breed. Pullets are female chickens that haven’t reached adulthood. Male chickens become cocks or roosters after full maturity.

Chickens give different warning calls to indicate that a predator is approaching from the air or on the ground. Chickens are capable of mobbing and killing a weak or inexperienced predator, such as a young fox. Modern varieties however grow much faster; by day 35 a Ross 708 broiler may weigh 1.8 kg (4.0 lb) as against the 1.05 kg (2.3 lb) of a heritage chicken of the same age. Newly hatched chicks of both modern and heritage varieties weigh the same, about 37 g (1.3 oz). 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. The word chicken comes from Old English cicen (pronounced essentially the same as in Modern English).

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.

Subsequent ovulations may occur within an hour after the previous egg was laid, allowing some hens to produce as many as 300 eggs per year. Egg laying is stimulated by the long stretches of daylight that occur during the warmer months; however, artificial lights placed in chicken coops can trigger a hen’s egg laying response throughout the year. Although many taxonomists and ornithologists consider it as a domesticated form of the wild red jungle fowl, some classify it as a subspecies of the red jungle fowl (i.e., G. gallus domesticus), whereas others, including the U.S. In the process of domestication, chickens were apparently kept initially for cockfighting, and only later used for food. Many people obtain chickens for their egg production but often name them and treat them as any other pet like cats or dogs.

Unfortunately, that can mean falling into a dinner rut much too easily for our liking. Always ask a veterinarian for help regarding your birds. Straight-run chicks are unsexed chicks bd chicken road whose gender is unknown, so it’s hard to establish the gender of such chicks. Pullet is a term that refers to a young hen that is yet to reach sexual maturity. Here is how to classify these birds based on sex and age.
