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.
Backcrossing of many generations of the hybrid Bekisar males with feral domestic game hens must occur before fertile females are produced. Female hybrid offspring of green junglefowl crossed with domestic fowl are always sterile, laying eggs that are incapable of being fertilized by either green or red junglefowl, or by domestic fowl.
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.
Koen Vanmechelen (born August 26, 1965 in Sint-Truiden) is a Belgian artist who began his career in the early 1990s.Central to his work is the concept of bio-cultural diversity, which he investigates through the domestic chicken and its ancestral species, the red junglefowl or Gallus gallus.
Gulls' eggs tend to have speckled shells (which somewhat camouflages them in the landscape), [1] a flavor variously described as fishy or salty that is reminiscent of the birds' marine environment, an especially white or even opalescent albumen when cooked, [2] and almost-red orange yolks. [3]
Monotremes, egg-laying mammals, lay soft-shelled eggs similar to those of reptiles. The shell is deposited on the egg in layers within the uterus. The egg can take up fluids and grow in size during this process, and the final, most rigid layer is not added until the egg is full-size. [citation needed]
