The week of Thanksgiving one of our Americana's started losing feathers on the back of her neck. We thought it was due to another hen trying to take her place at the top of the pecking order. After another day of watching though we saw that she was missing most of the feathers on her whole neck and some of her head, which led us to believe it was an early molt. (She's not even a year old). I thought it was perhaps a stress induced molt as 1) she never quite figured out the watering system they had and 2) was being fought pretty consistently by one other hen. We also thought that maybe it could be lice and treated her for that but no other bird showed any signs. Of course the week after she lost most of her feathers the temperature dropped significantly. Twenties have been the highs. She's spending all day inside the coop to try to keep warm but we can't get her to eat any food we give her. I've seen her come out a few times to get water (we changed their setup so she could figure it out) that's it. I know they're hearty and they keep each other warm at night but I'm worried about her. I've thought about bringing her inside just to monitor her water and food consumption. I know if she's not eating to keep warm and she has hardly any feathers there is a good chance she won't make it. I'm just curious if any one else has had a similar experience. What should l do?
