The red bits on a chicken's head are called combs and wattles. The comb is the mohawk-like red thing on top of a chicken's head, while wattles are the red fleshy bits that hang on either side of a chicken's throat or chin. Both combs and wattles are made of collagen fibres and help regulate the chicken's body temperature.

What You'll Learn
The red bits are called 'combs'
The red bits on a chicken's head are called combs. They are called combs because they resemble the shape of a comb, with their mohawk-like appearance. These combs are typically red or pink in colour, but they can also be darker or purple.
Combs are made of collagen fibres and have an outer layer of epidermis, similar to skin. They are sensitive to touch, and chickens may enjoy having them rubbed.
The primary function of combs is to help chickens regulate their body temperature. Chickens do not sweat, so they use evaporative cooling to prevent overheating. This involves increasing blood flow to the combs, which then release heat. When a chicken gets hot, its comb enlarges as blood pumps faster to cool the chicken down.
Combs also serve as indicators of a chicken's health and sexual maturity. A bright red comb is a sign of a healthy chicken. If the comb turns darker or purple, it may indicate an underlying health issue. In addition, the size and shape of combs can signal strength and vitality, making chickens more attractive to potential mates.

They help chickens regulate their body temperature
The red bits on a chicken's head are called combs and wattles. The comb is the red growth on top of a chicken's head, resembling a mohawk hairstyle. The wattle, on the other hand, is the fleshy red growth that hangs on either side of a chicken's throat or beak.
These red fleshy bits play an important role in helping chickens regulate their body temperature. Since chickens do not have sweat glands, they cannot cool down by sweating like humans do. Instead, they rely on evaporative cooling to regulate their body temperature. This process involves increasing blood flow to the combs and wattles, allowing moisture on the surface of their lungs to turn into vapour. When chickens get hot, their combs and wattles enlarge as blood pumps faster to release heat. This enlargement of the combs and wattles helps to cool the blood, which then circulates back to the rest of the chicken's body, preventing overheating.
The size and shape of combs and wattles can vary depending on the breed and individual characteristics of the chicken. In roosters, these features are often larger and more noticeable than in hens. The colour of the combs and wattles can also vary, ranging from bright red to pink or purple shades. A healthy chicken typically has vibrant red combs and wattles, while a darker or purple colour may indicate illness.
In addition to temperature regulation, combs and wattles also serve other important functions. They communicate the health and sexual maturity of the chicken, indicating high testosterone levels and good egg production. These features attract potential mates and signal vitality and strength. The blood flow to the combs and wattles can also provide information about the chicken's circulatory health, helping to identify any underlying issues.

They communicate the chicken's health
The red bits on a chicken's head are called combs if they are on top of the head and wattles if they hang on either side behind the beak. Both combs and wattles are made of collagen fibres and are integral to the health and survival of chickens.
Firstly, the colour of the combs and wattles can indicate a chicken's health. A nice bright red comb is a sign that the chicken is healthy. If the comb is turning black or purple, it could indicate illness. Similarly, a change in the appearance of wattles could indicate an underlying health issue.
Secondly, combs and wattles help chickens regulate their body temperature. Chickens do not have sweat glands, so they use evaporative cooling to prevent overheating. This involves turning the moisture on the surface of their lungs into vapour and increasing blood flow to their combs and wattles. The blood from the comb then circulates lower to the wattles, where it is cooled. This process is important for keeping chickens comfortable on hot days.
Thirdly, combs and wattles indicate the point of sexual maturity in chickens. In roosters, pronounced wattles signal high testosterone and proper nutrition, making the cockerel an attractive mate. In hens, red wattles communicate the potential for good egg production.
Finally, combs and wattles can help identify whether a chicken has circulatory issues. Since combs respond to blood flow, a change in colour can indicate potential issues with the circulatory system.

They signal sexual maturity
The red bits on a chicken's head are called combs and wattles. The comb is the mohawk-like or fleshy growth on top of a chicken's head, while wattles are the red bits that hang on either side behind the chicken's beak or throat.
Both combs and wattles have a vibrant red colour, although the shade can vary from bright red to pink. In some cases, the colour may be darker, such as purple or black, which can indicate an underlying health issue.
These red growths serve multiple purposes. Firstly, they assist in thermoregulation by helping chickens remain cool. This is achieved through evaporative cooling, where blood flow to the combs and wattles increases, allowing moisture on the surface of the lungs to turn into vapour. This process is crucial for chickens since they do not have sweat glands like humans.
Additionally, combs and wattles play a role in signalling sexual maturity and health. In roosters, prominent wattles indicate high testosterone levels and proper nutrition, making them attractive to hens. In hens, red wattles suggest good egg production. Thus, these features not only communicate health and vitality but also enhance the attractiveness of both hens and roosters to potential mates.
Furthermore, combs and wattles can provide insights into a chicken's health. For example, changes in colour or appearance may indicate dehydration or other health issues. As they are composed of collagen fibres, these structures are sensitive to blood flow changes, allowing for the detection of circulatory problems.

The fleshy bits that hang on either side of a chicken's throat are called 'wattles'
The red, fleshy bits that hang on either side of a chicken's throat or chin are called wattles. They develop within the first month of a chick's life and continue to grow until the chicken reaches full maturity. Wattles are similar in appearance to combs—the mohawk-like growths on top of a chicken's head—but they hang down from the sides of the throat or chin.
Both male and female chickens have wattles, but the wattles on male chickens (roosters) tend to be larger and more noticeable. The size and shape of a chicken's wattle vary depending on the breed and individual characteristics of the bird.
Like combs, wattles have an important function in regulating a chicken's body temperature. Chickens do not sweat like humans do, so they use evaporative cooling to prevent overheating. This involves increasing blood flow to their wattles and combs, which then release heat. When a chicken gets hot, blood pumps faster to these areas, causing the wattles and combs to enlarge.
The colour of a chicken's wattles can also indicate its health and sexual maturity. In most hens, wattles are a vibrant red, but they can also be rosy or pink. Roosters with pronounced wattles signal high testosterone and proper nutrition, making them attractive mates. If the colour of a chicken's wattles changes, it may indicate an underlying health issue.
