Sorry if this seems like a dumb question. We just got our 4 hens in May so we are new to chicken keeping. All of the hens were newly laying when I bought them and I noticed the black Australorp had poultry lice after getting them. She had lost some feathers in the vent area due to the lice and her picking at them. After multiple treatments we finally took care of the lice and somehow none of the others got them. Anyways she has been losing feathers like crazy and just hasn't been herself. Can someone please tell me what's going on?
