As with other jungle fowl, Sri Lankan jungle fowl are primarily terrestrial. They spend most of their time foraging for food by scratching the ground for various seeds, fallen fruit, and insects. Females lay two to four eggs in a nest, either on the forest floor in steep hill country or in the abandoned nests of other birds and squirrels. Like ...
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.
A gene from the gray junglefowl is responsible for the yellow pigment in the legs and different body parts of all the domestic chicken breeds. [14] A more recent study revealed multiple gray junglefowl genomic regions introgressed the genome of the domestic chicken, with evidence of some domestic chicken genes also found in the gray junglefowl ...
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.

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.
[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 ...

Ayam Kampong hens left to forage lay about 55 [7]: 9 or 100 [4] brown eggs per year, with an average weight of 39 g. [7]: 9 The poor performance as an egg producer is attributed to the broodiness of the hens. [4] In meat production, birds reach a market weight of 1–1.5 kg in three or four months. [4]
