Hi all, My girl Peach lost her feathers on the back of the neck a month or more ago. They look like they are trying to grow back but havent. I read about lice and mites, but dont see any. I gave her a looooonnng bath in vinegar/salt/soap and sprayed her with some pest spray made for chickens. I think she might be moulting now too. Here are some pictures. Even though I dont see lice and mites, could they still be the problem?
