Chickens have a fleshy growth called a comb on the top of their heads. They also have two thin, fleshy growths called wattles that hang down below their beak. Combs and wattles come in different shapes and sizes depending on the chicken's breed and sex. They are used for temperature control and can act as an indicator of a chicken's health. The comb is also used for mating purposes, as the size of the comb can indicate the chicken's reproductive health.

What You'll Learn
The comb and wattle are indicators of a chicken's health
The colour of a chicken's comb can indicate its health. A healthy comb will typically be bright red, although this may vary depending on breed. A pale comb can indicate anemia or a parasite infestation, while a bluish comb suggests poor circulation, and a white comb indicates frostbite. A comb with a purple tinge may be a sign of circulation problems, and a comb with black spots could be a symptom of fowl pox. The size of the comb can also be indicative of health issues; a laying hen will typically have a larger, brighter comb, while a small comb may indicate a serious health issue.
The wattle also provides insight into a chicken's health. In a laying hen, healthy wattles should be large, glossy, soft, and waxy. A floppy wattle may indicate injury or dehydration, and large wattles in a cockerel can be a sign of good nutrition and high testosterone levels.
In addition to health, the comb and wattle play a role in sexual attraction and mating. As a chicken matures, its reproductive hormones increase, causing its comb to grow bigger and fuller. Roosters typically have larger combs and wattles than hens, making them more attractive to potential mates.

They also indicate sexual attraction and reproductive health
A chicken's comb and wattle are indicators of its health and reproductive fitness. The comb is a fleshy growth on the top of a chicken's head, and the wattle is a fleshy flap of skin that hangs below the beak. Wattles usually come in pairs and hang on either side of the beak, although some chickens have a single wattle.
The comb and wattle function as a chicken's cooling system. Chickens do not sweat, so they cool themselves by circulating blood through the comb and wattle, which then transfers heat to the surrounding air. The comb and wattle are composed of a network of arteries, veins, and capillaries that form a mini-circulation system, allowing for rapid heat exchange between the blood vessels. This system helps regulate body temperature in hot and cold weather.
The colour and appearance of a chicken's comb can indicate its health and reproductive status. A healthy comb is typically bright red, firm, and rubbery to the touch, with an even colour and no marks or discolouration. A pale comb can indicate anemia or a parasite infestation, while a bluish comb suggests poor circulation or low temperatures. A white comb is a sign of frostbite, and a dry, shrivelled, or flaky comb may indicate poor health or a circulatory problem. A bright comb in a laying hen indicates good health, and in roosters, it signals virility and health, making them more attractive to hens.
The wattle also plays a role in sexual attraction. Larger wattles in cockerels indicate good nutrition, high testosterone levels, and potential reproductive success, making them more appealing to hens.
In summary, the comb and wattle of a chicken are important indicators of its health, reproductive status, and sexual attraction. They play a vital role in regulating body temperature and are visually attractive to potential mates.

Combs and wattles vary in shape and size depending on breed
Combs and wattles vary in shape and size depending on the breed of chicken. The comb is a fleshy organ located on the top of a chicken's head, and the wattle is a fleshy flap of skin that hangs below the beak. While wattles typically come in less variety than combs, they can still differ in shape and size. For instance, some chickens have long, oblong-shaped wattles, while others have short, rounded ones. Wattles are usually paired and hang on either side of the beak, but some chicken breeds have a single wattle. Bearded chicken breeds often lack wattles or have very small ones that are barely visible among their beard feathers. Faverolle chickens, Silkies, and bearded-Polish chickens are examples of breeds with little to no wattles.
The size and shape of combs and wattles are influenced by factors such as breed, sex, and individual variation. Roosters generally have larger combs and wattles than hens of the same breed. Hormones play a role in comb growth, with reproductive hormones causing the comb to enlarge as a chicken matures. Cockerels typically experience these growth hormones sooner than pullets, resulting in larger combs at an earlier stage.
In addition to sex-related differences, the size and shape of combs and wattles can vary significantly across breeds. Mediterranean chickens, such as Leghorns, Minorcas, and Anconas, tend to have larger combs, while cold-hardy birds like Icelandic, Ameraucana, and Chantecler chickens have smaller combs. The shape of combs can also differ, with some breeds sporting walnut combs, cushion combs, strawberry combs, or round lumpy combs, like those found in Silkies.
The comb and wattle play essential roles in a chicken's health, reproduction, and temperature regulation. They serve as indicators of a chicken's health status, with the colour and texture providing clues about potential issues. Additionally, the comb and wattle function as a natural air conditioning system, helping chickens regulate their body temperature by circulating blood through these fleshy areas.

They help chickens regulate their body temperature
The comb and wattle on a chicken's head serve multiple purposes, one of which is temperature regulation. Chickens do not sweat like humans do. Instead, they cool themselves by circulating blood through their comb and wattles. The comb and wattle function as a natural air conditioning system or a radiator, allowing heat to be transferred to the outside air. This helps the chicken maintain its body temperature during hot summers and cold winters.
The comb is a fleshy growth or crest located on the top of a chicken's head. It is considered an organ, consisting of a network of arteries, veins, and capillaries that form a mini circulation system. This system allows for rapid heat exchange between the blood vessels. Blood is pumped into the comb and temporarily held there through a network of shunts that open and close as needed.
The wattle is also a fleshy growth, but it hangs down under the chicken's chin or beak. Wattles are usually found in pairs, one on each side of the beak. While the shape and size of wattles can vary depending on the breed, they generally help with body temperature control, similar to the comb.
The size and colour of a chicken's comb and wattle can also provide insights into the bird's health and reproductive status. For example, a healthy comb is typically firm, rubbery, and brightly coloured, while a pale or discoloured comb may indicate anaemia or a parasite infestation. Additionally, during the fall molt or shorter winter days, a hen's comb may shrink in size, indicating that she has stopped laying eggs.
In summary, the comb and wattle of a chicken play a crucial role in temperature regulation, and they achieve this through a unique circulatory system that helps the bird stay cool during hot weather and maintain body temperature during cold weather.

Dubbing is the practice of cutting a chicken's comb and wattle
A chicken's comb is a fleshy organ located on the top of its head. Combs come in different shapes and sizes depending on the chicken's breed and sex. The comb is always located at the top of a chicken's head but there are nine different recognized comb types (determined by breed) and there can be several different varieties within each one. The comb is used to keep the chicken cool in hot weather as chickens do not sweat.
A chicken's wattles are the fleshy skin that hangs below a chicken's beak. Wattles are in pairs and hang on either side of the beak. Wattles also help to cool the bird down. Blood circulating from the comb to the wattles is cooled and helps to lower the temperature during hot weather.
In recent years, dubbing has faced criticism from animal welfare organizations. The Farm Animal Welfare Council (FAWC) in the UK, for example, believes that the practice should be phased out as it offers no welfare advantages to offset the disturbance and pain caused. Similarly, the European Food Safety Authority (EFSA) has concluded that dubbing should not be carried out unless justified by evidence of a substantial and unavoidable level of poor welfare in the birds.
