Ever wondered what the red things on top of a chicken's head are called? Well, they're called combs, and they serve a very important purpose. These fleshy protuberances help chickens regulate their body temperature, acting like a radiator to keep them cool in hot weather. They also have some sex appeal for chickens, with their appearance communicating health and sexual maturity.

What You'll Learn
The 'comb' is the fleshy red area on top of a chicken's head
The comb is the fleshy red area on top of a chicken's head. It is an organ, and it helps chickens regulate their body temperature in the heat. As the comb sticks up, away from the head, blood flows into it and cools. The comb acts like a car radiator, and its large surface area allows heat to be released. The comb also has some sex appeal for chickens.
There are several different types of chicken combs, including the single comb, buttercup comb, strawberry comb, rose comb, and pea comb. The single comb is the most common, and it consists of a series of spikes that run from the chicken's beak to the back of its head. The combs of Silkie chickens, a small breed, are a very dark maroon red. Both male and female chickens have combs, but they are larger in males.
The colour of a chicken's comb can indicate its health. A grown chicken's comb should be red, and if it looks pale, it may be unwell. Similarly, a comb that changes colour can indicate illness. Combs are also prone to frostbite in cold weather, and parts of them may turn black and fall off.
Under the chicken's beak are two more fleshy lobes of skin, called wattles. These are usually red but can also be other colours, such as blue, maroon, or black. Like the comb, they aid in regulating body temperature, and changes in their appearance can indicate health issues.

Combs have different types, including single, buttercup, strawberry, rose and pea
The soft, tall red points on top of a chicken's head are called combs. They help chickens regulate their body temperature in the heat by allowing blood to flow into them and cool down. Combs are considered organs because they perform such a vital function.
The shape of a chicken's comb may vary depending on the breed. Some combs are floppy, upright, double, shaped like horns, or crumpled and close to the head. For example, rose combs are crumpled-looking and tight to the head. Chicken breeds with small combs close to the head were often developed in cold countries as large combs are prone to frostbite.

Combs help chickens regulate their body temperature
The soft, tall red points on top of a chicken's head are called combs. They help chickens regulate their body temperature in hot weather. As the comb sticks up, away from the chicken's head, blood flows into it and cools. This process is called evaporative cooling.
Chickens have a naturally warm body temperature of about 105°F. They do not have sweat glands, so they rely on other methods to regulate their body temperature. They use their feathers, breath, and blood to cool themselves down. During cold weather, chickens will fluff up their feathers to trap warm air against their bodies. In hot weather, they do the opposite, keeping their feathers sleek against their bodies to let a breeze ruffle them and pull trapped heat away.
Chickens also use their combs and wattles (the fleshy red lobes of skin found under the beak) to regulate their body temperature. Combs and wattles are highly vascularized, and chickens will engorge these blood vessels with warm blood during warm weather. When a breeze or cool mist runs over the engorged blood vessels, heat is pulled away from the chicken's body.
In addition to using their combs and wattles for evaporative cooling, chickens also cool themselves internally through a process called excretory heat transfer. They drink lots of water, which passes through their digestive tract and exits as loose, watery droppings. This helps them stay cool.
Chickens also employ behavioural modifications to stay comfortable. When they are too warm, they will eat less, lift their wings, and move away from each other to improve airflow. When they are too cold, they will eat more, ruffle their feathers to trap warm air, and huddle together for warmth.

Wattles are the two fleshy lobes of skin found under a chicken's beak
Like combs, wattles help regulate a chicken's body temperature. When the comb and wattle change colour, or the wattle shrinks or changes in appearance, it may indicate health issues.
The comb is the fleshy red area at the top of a chicken's head. Combs are larger in male chickens and vary in shape and size depending on the breed. They help chickens regulate their body temperature by allowing blood to flow into them and cool down. Combs are considered organs because of their vital function in temperature regulation.
Chickens do not have teeth. Instead, they have a triangular tongue with tiny barbs that help them move food to the back of their mouths. They also use their beaks to groom themselves by running their feathers through them.

Chickens have beaks instead of teeth
Inside the beak is a triangular-shaped tongue with tiny barbs that catch and move food to the back of the mouth. Chickens have few taste buds, so their sense of taste is limited. At the top of the beak are the chicken's two nostrils, surrounded by a raised tan patch called the cere. The nostrils may be partially hidden by the bottom of the comb, and in birds with topknots, the nostril caverns are much larger.
The comb is the fleshy red area at the top of a chicken's head. It serves as a radiator, helping to cool the chicken by circulating blood through its large surface area. Combs come in various shapes and sizes, including single, buttercup, strawberry, rose, and pea. The shape and size of the comb depend on the breed of chicken and whether the chicken lives in a cold or warm climate. For example, chickens in cold countries tend to have small combs close to the head to avoid frostbite.
The wattles are the two fleshy lobes of skin found under the chicken's beak. They are usually red but can also be blue, maroon, black, or other colours depending on the breed. Like the comb, wattles help regulate the chicken's body temperature. Changes in the colour or size of the wattles can indicate health issues.
