I have about 6 hens who have bare backs due to molting and a highly ambitious rooster. This wasn't too big of a problem until they started hanging outside in the 70-80 degree sunny days. I have noticed in the last few days that their backs are stating to get very pink, some even red-purple, which on a human equals sun burn. Their skin is leathery and a little crunchy. I'm specially worried about one who looks like she has welts on her back. I'm not sure what else i can do other than lock them in a cool room for a few weeks and let the skin heal and the feather grown back. Has anyone else had this issue and have a trick up their sleeves? Thanks for any help/ideas.
