Crest on the top of the head of some gallinaceous birds
A comb is a fleshy growth or crest on the top of the head of some gallinaceous birds, such as domestic chickens. The alternative name cockscomb (with several spelling variations) reflects the fact that combs are generally larger on cock birds than on hens. The comb is one of several fleshy protuberances on the heads of chickens, the others being the wattles and earlobes, which collectively are called caruncles. In turkeys, the caruncles are the fleshy nodules on the head and throat.
Chicken combs are most commonly red, but may also be black or dark purple in breeds such as the Silkie or the Sebright. In other species the color may vary from light grey to deep blue or red.
The comb may be a reliable indicator of health or vigor and is used for mate-assessment in some poultry species.
