High Quality Content by WIKIPEDIA articles! The Red Junglefowl (Gallus gallus) is a tropical member of the Pheasant family. They are thought to be ancestors of the domestic chicken with some hybridisation with the Grey Junglefowl. The Red Junglefowl was first raised in captivity at least several thousand years ago in Asia, and the domesticated form has been used all around the world as a very productive food source for both meat and eggs. Some breeds have been specifically developed to produce these.
