Animal Names Glossary

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. It comes in two varieties, the rose comb and the single comb. Ancona is a widespread breed belonging to the Mediterranean class. They include Leghorns, Catalans, Andulusians, and Anconas. They include Cornish, Australorp, Sussex, and Orpington.

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. Altercations, however, may also include pummeling with wings and scratching with claws. A flock usually includes one dominant adult male, a few subdominant males, and two or more females that are carefully watched over by the dominant male. Chicks are born covered in down, but they mature quickly, becoming fully feathered after four to five weeks.

After 12 months of laying, the commercial hen’s egg-laying ability declines to the point where the flock is commercially unviable. Genomic studies estimated that the chicken was domesticated 8,000 years ago in Southeast Asia and spread to China and India 2,000 to 3,000 years later. Fertile chicken eggs hatch at the end of the incubation period, about 21 days; the chick uses its egg tooth to break out of the shell. Individual chickens dominate others, establishing a pecking order; dominant individuals take priority for access to food and nest sites.

Mature males have long been used for sport (i.e., cockfighting, now outlawed in many jurisdictions) as well as for breeding. Modern high-volume poultry farms, with rows of cages stacked indoors for control of heat, light, and humidity, began to proliferate in Great Britain about 1920 and in the United States after World War II. Descendants of those domestications have spread throughout the world in several waves for at least the last 2,000 years. In situations where one adult bird challenges another—which happens 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 domesticating the chicken, humans took advantage of the red junglefowl’s ability to reproduce prolifically when exposed to a surge in its food supply.
• This involves the sacrifice of a sacred rooster, often during a ritual cockfight, used as a form of communication with the gods.
• A hen is sexually active, and it has started laying.
• These domesticated chickens spread across Southeast and South Asia where they interbred with local wild species of junglefowl, forming genetically and geographically distinct groups.

Classifications of Chickens

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.

Sexed Chicks and Straight-Run Chicks

Some breeds, such as the Cochin, Cornish and Silkie, regularly go broody and make excellent mothers. During this time, the newly-hatched chicks live off the egg yolk they absorb just before hatching. All the time she is sitting in the nest she will regularly turn the eggs keeping them at a constant temperature and humidity. When a hen becomes familiar coming to his ‘call’ the rooster may mate with the hen and fertilize her egg. Removing hens or roosters from a flock causes a temporary disruption to this social order until a new pecking order is established. Chickens have a communal approach to the incubation of eggs and raising of young.
