I have a 9 week old chick that was picked at because she got stuck in a netting...feathers on wing 1 layer left. Looks like her back is bald under her wing. Not sure what to do about winter. Blood has scabbed over and I'm thinking of trying her out there again. I thought it was crazy but I saw chicken sweaters and am wondering if that will keep her warm enough for winter. I'm afraid she'll freeze to death without her feathers there.
