Loosing Feathers

[Nate Caskey]

I have a 1 year old Black Austrolorp and she has been loosing feathers on her back and belly. At first I thought it was the rooster pulling them out because she has always been resistant to him when he wants to mate. The. She started loosing the feathers on her sides and belly. I don’t see any mites on her, but it doesn’t seem to be getting better. Any thoughts?

It still looks like overmating. Especially in front of the tail. The breast feathers missing may have something to do with where she is roosting. What are they being fed?
It won't likely improve until she molts.
What is your rooster/hen ratio?
