Kind of new to chickens. Just picked up 2 hens from an egg farm that were getting rid of their older flock.:/ 1 hen looks great, the other seems to have been getting "pecked" on. All of her tail feathers are gone and her "butt" is bare. Is there anything I can do to make sure she is ok? To me it looks like red inflamed skin, but I don't know know if that is normal or not. No blood, just raw.
