Why do chickens feathers turn white?

The most common cause of white feathers in chickens is genetics. Some breeds of chickens, such as the White Leghorn, have a dominant white gene that causes all of their feathers to be white. Other breeds, such as the Rhode Island Red, have a recessive white gene that only expresses itself when two copies of the gene are inherited.

Age

As chickens age, their feathers can start to turn white. This is a natural process that is caused by the breakdown of melanin, the pigment that gives feathers their color. The rate at which feathers turn white varies from bird to bird, but it typically starts around the neck and head and then progresses to the rest of the body.

Stress

Stress can also cause chickens' feathers to turn white. Stressful events can include things like:

* loud noises

* extreme temperatures

* illness

* poor nutrition

* overcrowding

Diet

A lack of certain nutrients can also cause chickens' feathers to turn white. These nutrients include:

* protein

* methionine

* cysteine

* tyrosine

If you are concerned about your chicken's feathers turning white, you should talk to your veterinarian. They can help you determine the cause and recommend the best course of action.
