Alright my issue here is that my chickens seem to have lost their feathers during the molt season. Which is natural, but it's getting hot where I am at and I worry. They lost their feathers going into fall and they don't seem to be able to recover. The rooster are fatherless on their backs, necks and their wings are messed up. While the hens are completely bald on their backs and some on their butts. I have been feeding them higher protein feed and given them oyster shells. I am worried it may be a parasite or disease.
