What Causes Chickens to Lose Feathers

One of the most frustrating things that can happen to a chicken keeper is finding out why their chickens are losing feathers. Chickens rely on their feathers for insulation, waterproofing, and camouflage so when they lose them we want to make sure it’s for a healthy reason. A chicken losing feathers can signify poor health or an underlying condition so it’s important to find out why they might be losing them. Some of the most common reasons why chickens lose feathers include:


Chickens typically molt (lose and grow new feathers) once or twice a year. The amount of daylight can influence molting, so it’s not unusual to see molting occur in the fall as the days get shorter. While molting is a natural process, it can be stressful for chickens and may cause them to lose more feathers than usual. However, overall it is a common and normal thing. Here’s an educational video going over what to expect when it comes to chicken molting:

Feather mites are tiny parasites that live in the shafts of feathers. They cause irritation and itchiness, leading to excessive preening and feather loss. It’s important to get rid of these as soon as possible to ensure the safety and health of your chickens.

Keeping an eye out for things like mites and lice is essential to keeping your chickens healthy. Especially as these can spread fairly easily and quickly to other chickens.
Chicken lice are more significant than mites and live on the skin, not the feathers. They cause irritation and intense itching, leading to feather loss. You’ll notice your chickens scratching and that they’re losing feathers. Getting treatment for the lice as soon as possible is essential. 


Like humans, chickens can experience stress from time to time. Common sources of stress for chickens include changes in their environment (such as a move to a new coop), sudden changes in temperature, predator scares, and overcrowding. When stressed, chickens may start picking at their feathers or engage in other self-destructive behaviors that can lead to feather loss.

Nutritional Deficiencies

A lack of certain nutrients in the diet can lead to feather loss. Nutritional deficiencies are often seen in chickens fed a poor diet or not given enough access to greens and other fresh foods. Nutrients from a well-balanced diet are used to grow their feathers thick and shiny.


Several diseases can cause feather loss in chickens, including Newcastle disease, infectious bronchitis, and avian influenza. If you suspect your chicken is sick, contact a veterinarian for help.
