I've had most all my hens lose feathers and the majority of the time it seemed to be in the winter time. But my green egg layer is losing hers in a way I've not seen. It's not just her down type feathers. It's all of um. Much more and she will be completely plucked. She would be ready for cooking short of gutting her. I've checker her and looked close at her feathers and don't see any mites so I'm wondering do some chickens go to this extreme? I've had her almost 2 years and this is the first time for this. She acts a little listless and really layed back in her movements. Not really peppy. I've got a bald head now I got a bald chicken. Any ideas?
