found: Britannica, viewed November 15, 2022(chicken, (Gallus gallus), any of more than 60 breeds of medium-sized poultry that are primarily descended from the wild red jungle fowl (Gallus gallus, family Phasianidae, order Galliformes) of India. The chicken is perhaps the most widely domesticated fowl, raised worldwide for its meat and eggs. There is some debate about what the chicken's scientific name should be. Although many taxonomists and ornithologists consider it as a domesticated form of the wild red jungle fowl, some classify it as a subspecies of the red jungle fowl (i.e., G. gallus domesticus), whereas others, including the U.S. Department of Agriculture, classify the bird as G. domesticus.)
