Chickens have a distinctive piece of skin that hangs down from the neck, known as a wattle. This feature is common to both hens and roosters, although the wattle is larger in males. The wattle is a cooling mechanism for chickens, as they do not sweat. The skin is similar in function to the comb on top of a chicken's head, which also helps to regulate body temperature.

wattle''>The skin is called a 'wattle'
The skin under a chicken's neck is called a wattle. Both hens and roosters have this feature, although the wattle is larger in males. The wattle is a fleshy lobe of skin that usually appears red, although it can also be brown, blue, maroon, black, or other colours depending on the breed. The shape and size of the wattle vary across breeds, and it serves as a cooling system for chickens.
Since chickens do not sweat, the wattle helps regulate body temperature. Blood circulates close to the surface of the skin in this area, allowing the surrounding air to cool the chicken's blood during hot weather. Similar to the comb on the top of a chicken's head, the wattle's colour can change due to illness. A healthy wattle is soft, blemish-free, and deep red, indicating good blood flow.
The wattle also plays a role in attracting potential mates. Roosters use their wattles for courtship displays, and hens tend to ignore roosters with small wattles. Instead, they favour roosters with large and bright-coloured wattles, which signify health and vitality.
In addition to its aesthetic and thermoregulatory functions, the wattle may also provide some protection to the chicken's neck and head area. The specific shape and size of the wattle may offer some degree of shielding against predators or environmental hazards.
Overall, the wattle is an important feature of a chicken's anatomy, serving multiple purposes, including temperature regulation, courtship, and potential protection.

Wattles are the chicken's cooling system
Chickens have a unique way of regulating their body temperature. Unlike humans, they do not sweat. Instead, they rely on their comb and wattles to cool themselves down. Wattles are the red, fleshy lobes of skin that hang below a chicken's beak. They vary in size and shape depending on the breed and are generally larger in roosters than in hens. Roosters use their wattles to attract potential mates.
The comb and wattles serve as the chicken's cooling system. When the weather is hot, blood circulates close to the surface of the skin in this area, transferring heat to the outside air and thus cooling the chicken down. This process is similar to the radiator in a car.
To help chickens cool down during hot weather, chicken keepers can take several measures. Providing access to cool water is essential, as chickens dunk their heads in the water to cool their wattles and combs immediately. Keeping the coop cool by using fans or evaporative coolers is also recommended. Additionally, chicken keepers can wet the chickens' underwings, combs, wattles, and feet with cool water and provide shade for the birds.
The colour of a chicken's comb and wattles can indicate its health. A healthy wattle is typically deep red, soft, and blemish-free, indicating good blood flow. A pale or discoloured comb or wattle can be a sign of illness or stress. Chicken keepers should also watch for changes in the size or appearance of the wattles, as this may indicate health issues.
In summary, wattles play a crucial role in a chicken's cooling system by facilitating blood circulation and heat transfer during hot weather. Chicken keepers need to be vigilant about the birds' health during hot weather and take appropriate measures to ensure their well-being.

They are larger in male chickens
The skin under a chicken's neck is called a wattle. They are two oblong fleshy appendages that hang below the chicken's chin. Wattles are similar to combs, the soft, tall red points on top of a chicken's head. Combs and wattles are vital for a chicken's survival as they help regulate the bird's body temperature. The comb and wattle are packed with blood vessels, allowing the blood to be cooled by the air before travelling through the bird's body.
While both male and female chickens have combs and wattles, there are differences in size and colour depending on the breed and gender. Roosters typically have larger wattles than hens of the same breed. A rooster's wattle is the same colour as the fleshy skin or comb on its head. The shape and size of the wattle also vary depending on the breed. For example, some chickens have long, oblong wattles, while others have shorter, more rounded ones.
The wattle serves multiple functions for male chickens. Firstly, it helps regulate body temperature. Secondly, it serves as an indicator of health. A healthy wattle is soft, blemish-free, and deep red, indicating good blood flow. Any discolouration or changes in appearance can signal health issues. Finally, the wattle plays a role in attracting potential mates. Roosters with larger and brighter wattles are seen as healthier and more attractive to hens.
In addition to these functions, the wattle can be susceptible to injuries due to its high number of blood vessels. Cuts on the wattle can bleed profusely, requiring quick action to stop the bleeding. To summarise, the wattle is an essential feature of a chicken's anatomy, providing insights into the bird's health, aiding in temperature regulation, and influencing mate selection.

Colour indicates health
The skin under a chicken's neck is often referred to as the "wattle," and it can vary in colour from pale yellow to red, depending on the breed and the chicken's overall health. A healthy wattle should be firm, smooth, and supple, and the colour can provide insights into the bird's circulation, respiratory function, and overall wellness.
A bright, vibrant red wattle is often a sign of good health and indicates proper blood circulation and oxygenation in the bird. This colour is due to a combination of good blood flow and a healthy amount of haemoglobin in the blood, which is responsible for the red colour and carries oxygen throughout the body. A vibrant red wattle is often seen in active, healthy birds with strong respiratory and cardiovascular systems.
However, a pale or whitish wattle can indicate anaemia or a lack of adequate blood flow to the area. Anaemia can be caused by various factors, including nutritional deficiencies, internal parasites, or genetic factors. A pale wattle may also indicate that the chicken is dehydrated, as proper hydration is crucial for healthy blood volume and circulation. In these cases, a review of the bird's diet and access to water may be necessary, and supplements or veterinary advice could be required.
A yellow or orange hue to the wattle can also provide insights into a chicken's health. Carotenoids, which are pigments found in many fruits and vegetables, can cause this colouration. Carotenoids are powerful antioxidants, and their presence in the wattle may indicate a diet rich in these beneficial compounds. Offering carotenoid-rich foods like carrots, sweet potatoes, or certain dark, leafy greens can enhance the colour and also provide health benefits to the bird.
That being said, a yellow or orange wattle can sometimes indicate jaundice, particularly if the skin and other tissues also show a yellow discolouration. Jaundice is often a symptom of liver disease or other underlying health issues, and it requires veterinary attention. In these cases, the yellow colouration is due to elevated levels of bilirubin, a breakdown product of red blood cells, which the liver normally processes and excretes.
In addition to these colour variations, any sudden changes in the wattle's appearance, such as swelling, bruising, or discolouration, could indicate trauma or infection. Bacterial or viral infections can sometimes cause swelling and redness, and in these cases, the wattle may feel hot to the touch. If the bird is displaying any other signs of illness or behavioural changes, it is always best to consult with a veterinarian, especially if the chicken is exhibiting respiratory symptoms or a decreased appetite.
In summary, the colour of a chicken's wattle can provide valuable insights into its health and wellbeing. While a vibrant red colour is often a positive sign, deviations from this can indicate nutritional deficiencies, dehydration, or, in some cases, more serious health concerns. Responsible chicken keepers should monitor the colour and condition of the wattle regularly and take prompt action if any concerning changes are observed.

comb'-on-their-head'>Chickens also have a 'comb' on their head
The skin under a chicken's neck is called a wattle. It is the red, fleshy skin that hangs down from the neck of a chicken, and it serves as the chicken's cooling system. Chickens do not sweat, so the wattle helps cool the blood by allowing air to circulate around it.
Chickens also have a comb on their head. The comb is made of soft collagen tissue and usually stands up on the chicken's head. It comes in many shapes and sizes and can be either an upright comb or a pendulous comb, which flops to one side. The comb helps the chicken regulate its body temperature in the heat. As the comb sticks up and away from the head, blood flows into it and cools. The comb is typically the same colour as the wattle, and changes in colour can indicate illness.
There are several types of combs, including the single comb, cup comb or buttercup comb, cushion comb, horn comb or V-comb, and leaf comb or shell comb. The shape and size of the comb vary depending on the breed of chicken. The comb and wattle serve the same purpose, and roosters use their combs to attract potential mates.
Combs are also used in cookery, often in combination with wattles or chicken kidneys. They are prepared by parboiling and skinning, then cooked in court-bouillon.
