Chicken

Presentation

The Chicken is one of the most common pets in the world. Originating from the domestication of the bankiva rooster from Southeast Asia, it has been selected for millennia for the production of eggs and meat. Today, hundreds of breeds coexist, offering a great diversity of shapes, colors and abilities.

The Chicken has dense and colorful plumage that varies greatly depending on the breed: red, black, white, gray or multicolored. It has a fleshy crest on its head, barbels under its chin, and scaly legs that are generally yellow or gray. Females are smaller and more discreet than roosters.

Characteristics

BREEDS

Indicative values: they vary by subspecies, sex and region.

Habitat and distribution

The Chicken adapts to many environments. In traditional breeding, it lives in henhouses and open enclosures with access to meadows or grassy areas. It prefers well-drained areas with protection from wind and predators.

Behaviour

Chickens are gregarious and hierarchical, establishing a strict social order called “pecking”. They spend a lot of time digging in the ground and bathing in dust for hygiene. They roast up high at night to protect themselves from predators.

Reproduction

Chickens reach sexual maturity around 5-6 months. An Chicken lays eggs regularly, usually 200 to 300 per year depending on the breed. The eggs hatch after 21 days of incubation. The chicks remain dependent on their mother for a few weeks before independence.

Peculiarities

The Chicken has almost total panoramic vision thanks to the lateral position of its eyes. It communicates through a variety of distinct vocalizations: cackling, clucking, cooing. The rooster has a more developed crest and wattles and utters distinct fighting songs.

Threats and conservation

As a domestic species without IUCN status, Chicken faces no conservation threats. However, intensive breeding raises animal welfare issues and diseases (avian flu) can affect breeding populations.
