Individual chickens in a flock will dominate others, establishing a "pecking order", with dominant individuals having priority for food access and nesting locations.
Removing hens or roosters from a flock causes a temporary disruption to this social order until a new pecking order is established.
In the UK and Ireland, adult male chickens over the age of one year are primarily known as cocks, whereas in the United States, Canada, Australia and New Zealand, they are more commonly called roosters. although in the egg-laying industry, a pullet becomes a hen when she begins to lay eggs, at 16 to 20 weeks of age.
In Australia and New Zealand (also sometimes in Britain), there is a generic term chook The species as a whole was then called domestic fowl, or just fowl.
Hens cluck loudly after laying an egg, and also to call their chicks. Under natural conditions, most birds lay only until a clutch is complete, and they will then incubate all the eggs. The broody hen will stop laying and instead will focus on the incubation of the eggs (a full clutch is usually about 12 eggs).
Chickens also give different warning calls when they sense a predator approaching from the air or on the ground. She will "sit" or "set" on the nest, protesting or pecking in defense if disturbed or removed, and she will rarely leave the nest to eat, drink, or dust-bathe.
Domestic chickens are not capable of long distance flight, although lighter birds are generally capable of flying for short distances, such as over fences or into trees (where they would naturally roost).
Chickens may occasionally fly briefly to explore their surroundings, but generally do so only to flee perceived danger.
Fowl had been known in Egypt since the mid-15th century BC, with the "bird that gives birth every day" having come to Egypt from the land between Syria and Shinar, Babylonia, according to the annals of Thutmose III.There are more chickens in the world than any other bird or domesticated fowl.Humans keep chickens primarily as a source of food (consuming both their meat and eggs) and, less commonly, as pets.He does this by clucking in a high pitch as well as picking up and dropping the food. Hens will often express a preference to lay in the same location.This behaviour may also be observed in mother hens to call their chicks and encourage them to eat. It is not unknown for two (or more) hens to try to share the same nest at the same time.
