The red, fleshy growth hanging from a chicken's neck is called a wattle. Roosters and hens both have wattles, but roosters' wattles are often larger and more noticeable. The wattle is similar in appearance to the comb, the mohawk-like growth on top of a chicken's head, and serves a similar purpose. The wattle helps circulate blood around the chicken's head, keeping it cool in hot temperatures. The colour and size of a chicken's wattle can indicate its health, with a healthy wattle being soft, blemish-free, and deep red.

What You'll Learn
The red thing is called a ''wattle'
The red, fleshy growth hanging from a chicken's neck is called a wattle. Both roosters and hens have wattles, but they are often larger and more noticeable in roosters. The size and shape of the wattle vary depending on the breed of the bird and the individual characteristics of the chicken. A healthy wattle is typically soft, blemish-free, and a deep red colour, indicating good blood flow.
The wattle has a similar appearance to the comb, the red growth on top of a chicken's head. However, unlike the comb, the wattle hangs on either side behind the chicken's beak or throat. Young roosters tend to have more pronounced wattles, signalling health and sexual maturity. Bright and vibrant wattles indicate high testosterone, proper nutrition, and good egg production, making the chicken an attractive potential mate.
The wattle serves several important functions integral to the health and survival of chickens. Firstly, it helps with thermoregulation. The blood from the comb circulates down to the wattle, where it is cooled, preventing the chicken from overheating on hot days. Secondly, the wattle aids in improving blood flow by circulating blood around the chicken's head.
The wattle is also a form of communication among chickens. The size and colour of the wattle can help establish a dominance or pecking order among chickens of the same gender. Additionally, the appearance of the wattle can indicate the chicken's health. For example, a change in the wattle's colour or a limp wattle may signal dehydration or other underlying health issues.

It indicates good health
The red thing hanging from a chicken's neck is called a wattle. It is a fleshy growth that hangs on either side behind a chicken's beak. Wattles are similar in appearance to combs—the red, mohawk-like growth on top of a chicken's head—but they sort of flap down on both sides of a chicken's throat. The comb and the wattle share a unique purpose: they help circulate blood around the chicken's head, preventing the bird from overheating.
The colour and appearance of a chicken's wattle can indicate its health. A healthy wattle is soft, blemish-free, and deep red, indicating good blood flow. In young hens, the wattle grows and becomes a brighter shade of red as the hen matures. A bright red wattle can also indicate that a hen is actively laying eggs. In roosters, a large and bright wattle is a sign of health and sexual maturity, demonstrating high testosterone and proper nutrition, which makes the rooster an attractive mate.
When there is a change in the appearance of a chicken's wattle, it may indicate an underlying health issue. For example, if a usually vibrant red wattle becomes darker or purple, it could be a sign of circulatory issues or dehydration. A limp wattle can also indicate dehydration or old age.
In addition to their role in communicating health, wattles are also used in courtship and displays of dominance. Roosters with larger and more noticeable wattles are seen as more attractive to potential mates. Among chickens of the same gender, the size and colour of the wattle can help establish a dominance or pecking order.

It helps regulate body temperature
The red thing hanging from a chicken's neck is called a wattle. It is similar in appearance to the comb, the mohawk-like red thing on a chicken's head, but it flaps down on either side of a chicken's throat. The comb and wattle share a unique purpose in helping chickens regulate their body temperature.
Chickens do not sweat like humans do, so they rely on these fleshy, plump, and vibrant parts to prevent them from overheating. The wattle and comb work to improve the bird's blood flow by circulating blood around the chicken's head, which helps keep it cool during hot temperatures.
The colour of the comb and wattle can provide valuable insights into a chicken's health. For example, a darker colour approaching purple may indicate circulatory issues, while a limp and floppy comb could signal dehydration or old age. In addition, the size and colour of these features can indicate sexual maturity and vitality, making hens and roosters more attracted to one another.
Young roosters typically have more pronounced wattles, indicating high testosterone and proper nutrition, which makes them attractive mates. Similarly, in hens, vibrant red wattles can communicate the potential for good egg production.
In summary, the red wattles hanging from a chicken's neck play a crucial role in thermoregulation, health signalling, and mating rituals, contributing to the overall health and survival of chickens.

It's used in courtship
The red thing hanging from a chicken's neck is called a wattle. They are similar in appearance to combs—the red, mohawk-like growths on top of a chicken's head—but they hang on either side behind a chicken's beak. Young roosters have pronounced wattles, which signal health and sexual maturity. A healthy wattle is soft, blemish-free, and deep red, indicating good blood flow.
Both roosters and hens have wattles, but roosters' wattles are often larger and more noticeable. The size and shape of the wattle vary depending on the breed of the bird and the distinct characteristics of the individual animal. A rooster with a large and bright wattle is considered an attractive mate. According to the Smithsonian Magazine, chickens are naturally attracted to the rooster with the largest, most noticeable wattle.
Hens tend to ignore roosters with small wattles, as healthy roosters typically have larger and brighter wattles. The colour of a hen's wattle can also indicate whether or not she is laying eggs. When the wattle is bright red, it means the hen is actively laying eggs. If the wattle is pinkish and smaller, the hen is not laying.
In addition to indicating sexual maturity and health, wattles are also used in courtship. The size and colour of a chicken's wattle can help establish a dominance or pecking order among chickens of the same gender.

It's larger on roosters
The red things that hang on either side behind a chicken's beak are called wattles. They are similar in appearance to combs but differ in that wattles sort of flap down on either side of a chicken's throat. Wattles are larger on roosters than on hens.
Young roosters have pronounced wattles. They signal the rooster's health, demonstrating high testosterone and proper nutrition, which makes the cockerel an attractive mate. The size of the wattles, like the size of the rooster's comb, is related to testosterone. Size, therefore, is an indication of social status — the biggest, baddest rooster has the biggest, brightest comb and wattles.
Researchers have determined that hens base their choice of mates, in part, on characteristics of the comb. However, when it comes to wattles, their purpose is not as clear. Researchers at Australia's Macquarie University, led by K-Lynn Smith, suggest that wattles help a rooster gain a hen's attention while he's tidbitting. Tidbitting is a routine performed by roosters that consists of high-pitched, pulsating sounds combined with repeated rhythmic movements of the head and neck, during which the rooster picks up and drops a piece of food without eating it.
According to Smith, the rapid swinging of the wattle during tidbitting draws a hen's attention in two ways: it increases the apparent size of the rooster's head, and it increases the range of motion resulting from head bobbing. Hens respond more quickly to tidbitting males with normal or stationary wattles, less quickly to those with extra floppy wattles, and slowest to males lacking wattles. However, after the hen's attention is gained, she reacts about the same to each of the four animated chickens.
