I have a Rhode Island Red that we adopted after she was attacked by a dog and rode about 20 miles on the undercarriage of a dump truck. In fact she's the reason we have chickens at all. While most of her feathers have grown back in, it looks like shes going to have a 3" bald spot on her upper chest and shoulder. Any ideas what kind of problems this will is going to cause this winter? My daughters friend is actually knitting her a vest, lol. I'm on Long Island, NY.
