During the laying period, red junglefowl females lay an egg every day. Eggs take 21 days to develop. Chicks fledge in about 4 to 5 weeks, and at 12 weeks old they are chased out of the group by their mother — at which point they start a new group or join an existing one.
The chicken (Gallus gallus domesticus) is a large and round short-winged bird, domesticated from the red junglefowl of Southeast Asia around 8,000 years ago. Most chickens are raised for food, providing meat and eggs; others are kept as pets [1] or for cockfighting.
Junglefowl are the only four living species of bird from the genus Gallus in the bird order Galliformes, and occur in parts of South and Southeast Asia.One of the species in this genus, the red junglefowl, is of historical importance as the direct ancestor of the domestic chicken, although the grey junglefowl, Sri Lankan junglefowl and green junglefowl are likely to have also been involved.

Galliformes / ˌ ɡ æ l ɪ ˈ f ɔːr m iː z / is an order of heavy-bodied ground-feeding birds that includes turkeys, chickens, quail, and other landfowl.Gallinaceous birds, as they are called, are important in their ecosystems as seed dispersers and predators, and are often reared by humans for their meat and eggs, or hunted as game birds.
The red junglefowl of Southeast Asia is the wild ancestor of the domesticated chicken, the most important bird in agriculture, and the wild turkey similarly is the ancestor of the domestic turkey. Several species of pheasants and partridges are extremely important to humans.
An expedition through an unpredictable, perilous mountain range in Indonesia’s province of Papua led to the rediscovery of a critically endangered egg-laying mammal that hasn’t been seen for ...
The wild green junglefowl is a mangrove forest-adapted species. Unlike the red junglefowl, the ancestor of most domestic chickens, it is adapted for life with little fresh water. During the dry season, and also on arid volcanic islands, the green junglefowl gets most of its water from dew in the coastal fog on fruits and insects.
[20] [21] Generally, chicken breeds with white ear lobes lay white eggs, whereas chickens with red ear lobes lay brown eggs. [22] Although there is no significant link between shell color and nutritional value, often there is a cultural preference for one color over another (see § Color of eggshell below). As candling is less effective with ...
