Red Junglefowl Gallus gallus
The Red Junglefowl and it's fives subspecies have proved to be of more importance to man than any other species of bird. They have provided all the numerous varieties of domestic fowl that we have today. The original distribution of the Red Junglefowl was from the River Indus in Pakistan down through India, eastward across and down through Malaysia, Java, and the Lesser Sunda Islands. They are highly adaptable and can live at altitudes from sea level up to 6,000 feet (1,800 meters). They resemble, not surprisingly, barnyard chickens.
As aviary birds, they are amenable in every way, provided only one cock bird is in each aviary. The cock bird can be run with a number of hens. Red Junglefowl can be kept with other Pheasant species, such as Argus or Eared-Pheasants, with which they do not appear to quarrel.
It is interesting to note that not only has the Red Junglefowl provided man with his most improtant domestic bird, but it has also twice made major contributions to mankind's health. Studies on birds infected by mosquitoes with malaria led ICI to develope, in the late 1930s, the preventive and cure paludrine, which had a major effect on the outcome of the battles with the Japanese in the Burma Campaign.
More recent studies on Red Junglefowl led to the means by which the AIDS virus could be quickly identified in man.
Avicultural Notes
Minimum aviary size 150 sq. ft. (14m2)--can be smaller but grass will not survive due to scratching
Statis in captivity Numerous though the purity of some stock is doubtful
Full adult plumage First year although improves in the second year
Egg clutch size 8-10 eggs
Incubation period 19-21 days
Feeding habits As for poultry
