Cock-A-Doodle-Doo! What's The Purpose Of A Chicken's Comb?


Ever notice that large, flappy piece of flesh sitting perched atop a chicken's head? That fancy chunk of flesh is called a comb. And yet, you probably have no idea what it's for.

In just a moment, you will.

A chicken's comb serves two main purposes. The first mission of the comb is to help cool the animal. The flesh growth helps to circulate blood and release the stored heat from within the animal. The comb then emits this excess heat. In essence, the comb is like a radiator for blood. This generally explains why most combs are red, but some also come in black or dark purple.


The second function of the comb is to aid in the mating process. Male chickens, called roosters, have larger and often more pronounced combs. Female chickens see the comb as a sign of superiority. They're drawn to the biggest and flashiest of combs, guaranteeing the best roosters get the chance to breed the newest generation of chickens.

Of note, the chicken isn't the only bird with a comb. Other fowl like turkeys and pheasants possess them, much for the same purposes.
