Why Do Chickens Losing Feather

Effects Of Chicken Feather Loss

Did you know that feather loss might cause grave consequences for both the flock and the poultry farmer’s business?

Health problems

Chicken feathers are used to be a protective cover from sun, rain, cold, and injury. Without it, the flock might experience severe health issues like the ones listed below.

Egg-laying issues

Although issues in laying eggs are common for chickens, it is almost impossible to identify its cause if you don’t observe your hen’s behavior. This issue can happen due to stress and vitamin deficiencies.    


This one may seem like a light problem, but it is not. More often, cuts happen in areas that do not have protection from the feather. When your chicken loses feathers, then its skin becomes vulnerable to cut.

Since feather loss causes an open space in the chicken’s body or skin, they become much more susceptible to infections such as bacterial and fungal. They also become prone to parasitic diseases due to lice, worms, ticks, and mites.

Temperature change

As mentioned above, feathers serve as the protective gears of the flock. It is the controller of their body temperature. If they lose their feathers, there will also be an apparent imbalance in their system.   


Chickens experience overheating due to over-exposure to the sun. Since they are experiencing feather loss, some parts of their skin are overly-exposed to sunlight which is typically not the case.   


If you are asking yourself if a chick can freeze to death, the answer will be yes! Freezing is a state where the chicken feels too cold. It happens since there are not enough feathers to cover them from the breeze. 

More feeds

The analogy in this one is so simple. If a cock loses something, it must regain something. If you intend to grow its feathers back again, the chicken will need to eat plenty more than usual.

It is a struggle on the poultry farmer’s side. You will need to invest and allocate more budget to feed, vitamins, and other sources of nutrients to make their chicken healthy again.  

Natural Causes Of Feather Loss

It is necessary to understand that not all the time, feather loss is dangerous and should be a reason to panic. Hence, remind yourself that there are three natural causes of feather loss in the coop.


Preening is a behavior of birds that happens naturally. It is a process that occurs due to the movement of oil from the preen glands located at their tails to their feathers. It also ensures that all stringed barbules are aligned appropriately with the feathers.

Most importantly, due to the preening process, chickens can watch themselves out for parasites and other insects. Moreover, it makes the chicken look tidy as preening is also known as the cock’s natural grooming demeanor.


Another reason for feather loss is the process called molting. Although it may distress new poultry farmers, the familiar ones know that there is nothing to worry about because this occurs annually.

Molting happens every year for the sole reason that chickens need to change their feathers. The process may vary depending on each hen. Some of them take months to molt, but others go through it quickly in two weeks.

You can expect molting during fall or winter. During this period, unusual depletion of egg-laying may be observed because the proteins are designated to make new feathers. Hence, you should let the cock intake a protein-rich diet.

There are numerous stress factors that each chicken in the coop experiences. Unfortunately, these are also the most important reasons which are being overlooked and are not given the same priority as the others.

Some of these stressors are bright lights, loud noise, too high or too low temperature, crowded coops, lack of food and water, and infestations. Look out for these to avoid further damage to your flock and business.  

The environment in the coop plays a crucial role in making every individual hen healthy. It must be comfortable and sufficient for all the chickens. Coops are something that all backyard farmers should invest in.   

Remember that if humans are prone to stress, probably animals do too!

Inflicted (Unnatural) Causes Of Feather Loss

Chicken feathers may lose due to natural causes. Nevertheless, other reasons are inflicted only by themselves or others in the coop. Thankfully, these can be avoided if resolved immediately. Check out these four unnatural causes of feather loss.


Chickens get moody too! Once they’re on it, they pluck their very own feathers. Hens wait for their eggs to hatch while building them a nest made from their feathers. Remove the eggs from the coop immediately if you don’t want a broody hen.

Broodiness might be hard to spot if you don’t know what a broody hen looks-like. Here’s a tip: moody hens are bad-tempered and grumpy. They are always ready for a fight!

Dominance issues or bullying

Bullying also happens inside the coop! Chickens feel the need to establish power among them. They do this by plucking the feathers of those who are weaker.

As a poultry farmer, you will notice if the loss is caused by bullying or not. If there is any dried blood on the skin of the chicken and it is displaying unusual behavior like anxiousness, then it’s safe to conclude that the feather loss was due to dominance issues.

When this happens, it is much better to separate from the coop the dominant one than the weaker one. That way, the other cocks will be safe from danger.

Vent gleet

Cloacitis or vent gleet is a gastrointestinal condition in the chicken’s cloaca that causes it to inflame. Since the infection makes the vent reddish, it will naturally attract others or even the cock itself to pluck plumage on it. Avoid such things by darkening the coop first.

Mating is indeed normal even for chickens. However, if it becomes excessive and overzealous, then it might result in severe feather loss.

During the mating process, the rooster may pull too much plumage on the hen due to uncontrolled eagerness. Ensure that your hens will not get hurt by separating the aggressive roosters into a different coop.
