Chickens have two nostrils located on their beak, which they rely on more than is commonly believed. These nostrils are surrounded by a raised tan patch of skin called the cere. While chickens may not be the best sniffers in the animal kingdom, they do have a strong sense of smell, which they develop while still in their eggs. The shape of their nostrils varies depending on the breed, with some having slit-type nostrils and others having cavernous nostrils.
What You'll Learn

Chickens have two nostrils
Chickens have a strong sense of smell, which they develop while still in the egg. Their sense of smell is probably as good as a human's, according to recent research. However, their nostrils can become clogged with dirt, feed dust, small feed granules, or as a result of respiratory disease or sinus canker. To unclog their nostrils, chickens will usually sneeze or shake their heads. Owners can also use an eyedropper with warm water to loosen debris, followed by gentle probing with a toothpick or a feather.
The beak of a chicken is made from keratin and is equivalent to the jaw in mammals. It serves many purposes, including grooming, eating, drinking, and manipulating objects. The beak grows continuously throughout a chicken's life and may need to be trimmed to prevent damaging pecking.
Other notable features of a chicken's head include its comb, eyes, ears, wattles, and neck. The comb is a fleshy growth that serves as a cooling mechanism, as chickens cannot sweat. The comb tends to be larger in roosters than in hens, and its colour can vary from red to blue, purple, black, light grey, or dark maroon red. The eyes of a chicken are small and set on each side of the head, but they have a 300-degree field of vision and can see in colour. Chickens do not have external ears, but their ear canals are located behind their eyes and are covered by tufts of feathers.

Nostrils are located on the beak
Chickens have two nostrils located at the top of their beak, one on each side. The nostrils are surrounded by a raised patch of skin called the cere, which is usually tan in colour. The cere may be partially hidden by the bottom of the comb, which is the fleshy growth found on top of a chicken's head. Combs are typically red but can also be black, blue, purple, or light grey.
The beak is the chicken's equivalent of a jaw and is made from keratin. It serves many purposes, including grooming, eating, drinking, and manipulating objects. The beak continues to grow throughout a chicken's life, and it may need to be trimmed to prevent damaging pecking.
Chickens develop their sense of smell while still in the egg, and they rely on their nostrils more than previously believed. Their sense of smell is probably as good as a human's, according to recent studies.
Chickens can have clogged nostrils for various reasons, including inhaling feed dust or dirt, respiratory diseases, or sinus canker. Clogged nostrils can be cleared by using a small amount of warm water to loosen debris, and then gently removing it with a tool such as a toothpick or a feather.

Chickens have a good sense of smell
Chickens have two nostrils located on their beak, which they use to develop their sense of smell while still in the egg. Despite their small eyes, chickens have remarkable senses. They have a 300-degree field of vision without turning their heads, can see in colour, and have an extra UV cone that allows them to see many more shades than humans. They also have sophisticated hearing to interpret sounds and locate danger.
While their sense of smell is not as strong as their other senses, chickens do have a good sense of smell. Recent genetic research has found that chickens have many genes dedicated to interpreting odours, including a whole new set of olfactory genes not present in mammals. Scientists are still trying to understand the function of these genes and how well chickens can smell. However, it is estimated that they probably smell as well as humans.
Chickens use their sense of smell for various purposes. They can identify familiar and unfamiliar scents, especially when it comes to their food. They also use their sense of smell to find food, avoid predators, and form strong memories associated with odours. For example, chickens will react with fear and stress if they detect the scent of a predator and will try to find a safe area to hide. Additionally, chickens may use their sense of smell for social communication within their complex social order.
Chicken keepers should be aware of their chickens' sense of smell when introducing new bedding or feed. Chickens may initially have an aversion to new odours, but they will get used to them over time. While there are claims that chickens do not like the smell of certain herbs, such as lavender and catnip, there are also stories of hens choosing to nest among these very herbs. Therefore, fencing remains the only sure way to keep chickens out of an area.

Nostrils should be clean and open
Chickens have two nostrils located on their beaks. They develop their sense of smell while still in the egg, and this sense is probably as good as a human's. The nostrils are surrounded by a raised tan patch of skin called the cere. In some birds, the nostrils may be partially hidden by the bottom of the comb. Birds with topknots have much larger nostril caverns.
The nostrils should be clean and open. You will see dirt build up around the area, and you can wipe it away. Chickens will normally sneeze or shake their heads to unclog their nostrils. However, if something is stuck in their nostrils, it can become concrete-like, and picking it out can be challenging. There are a few reasons why a chicken's nostrils might be clogged: the bird has inhaled feed dust or small granules, it has inhaled dust or dirt from dust bathing, it has some type of respiratory disease, or it has sinus canker.
If your chicken has clogged nostrils, you can use an eyedropper of warm water to loosen debris or crust, and then gently use a toothpick to try and remove it. Continue with warm water as necessary. If you decide to do this, tie the chicken's legs together with a shoestring (not too tight) and then snugly wrap a towel around it. Be aware that there are one or two vertical dividers within the nostril area, so be sure not to push hard against those. Take a look inside the bird's opposite nostril to see how it is structured before starting to work on the clogged nostril.
Alternatively, you can pick up a small or medium-sized feather from the ground and use the base of the follicle as a cleaning tool. The base of a feather is smooth and not scratchy, but still small enough to fit. Start at the end towards the eyes and move forward toward the beak to avoid jamming something into the nostril. If something lodges temporarily during this process, you can usually dislodge it with a little more gentle prodding.

Clogged nostrils can be caused by dirt or disease
Chickens have two nostrils located on their beak, which they rely on for their sense of smell. While chickens have a strong sense of smell, it is not the best in the animal kingdom.
Chicken keepers have reported that their chickens' nostrils have become clogged with dirt after digging and scratching in the dirt. One chicken keeper recommends cleaning the nostrils with a gentle mist of salt water, which worked immediately. However, others advise against using Q-tips to clean the inside of the nostrils, as this can be dangerous. Instead, a chicken's nostrils can be cleaned with the base of a feather, which is smooth, small, and gentle. It is important to start at the end towards the eyes and move towards the beak to avoid jamming something into the nostril.
Clogged nostrils can also be caused by disease. Oral canker, a condition caused by the protozoal parasite Trichomonas gallinae, can cause lesions in the mouth, pharynx, oesophagus, and further down the digestive tract. These lesions can become extremely extensive, causing chickens to stop eating and drinking, which can lead to death. Other respiratory diseases that can affect chickens include infectious coryza, infectious laryngotracheitis, and swollen head syndrome.
