Signs your chickens have red mite.
You
may notice a couple of things, Firstly your egg production will start
to decrease, this is because the chicken needs to replace the blood
lost by the red mites, meaning less energy for egg production.
The
Chickens may also peck each other where they see the infestation, this
is commonly at the base of the tail feathers. It is important to treat
an infestation fast as it may lead to stress in the chicken.
