Rooster with red comb
Cockscomb is fleshy growth or a bead above the head of galliformes, especially turkeys, pheasants and domestic chickens. Cocks are generally larger in males than females. Chicken combs are red, but in other species colors may vary from light gray to dark blue, turkey combs can vary in color from bright red to blue. Cockscomb can also be an indicator of health for several types of birds. Pet chickens (Gallus gallus domesticus) are poultry that are usually kept by people to be used for the needs of their livelihoods. Pet chickens are direct descendants of one of the subspecies of partridge known as red jungle fowl or bangkiwa chicken (bankiva fowl). Cross-breeding between chicken races has produced hundreds of superior strains or pure strains with various functions; the most common are cut chicken (to be cut) and laying hens (to be taken for eggs). Ordinary chickens can also be crossbred with close relatives, green partridges, which produce a male sterile hybrid (rooster)
