We had two blue copper marans, Maude and Margeaux. They were inseperable since they hatched. We lost Maude on Christmas day. Margeaux was depressed and stopped laying for about two weeks after. She seems somewhat improved now, but still quiet and on her own most of the time. Yesterday afternoon I noticed that most of the feathers have been picked out of her neck. Would the other birds be picking on her because she's so subdued? Anything I can do? I'm worried about her.
