Hi everyone! I have two hens in the coop (out of 13) who have some areas right before their tails where their feathers are missing and it looks a little greyish...Sort of dusty. The skin is not bloody or crusty. One has a bald, small crusty spot on the back of her head where the BAD rooster would grab on to her, but I don't know if that's secondary to another skin condition. I'm not sure if this is molt, or something else. I don't see any ticks or lice on visual inspection, and not sure if this is molt. Otherwise, everyone is healthy with plenty of water and food consumption, lots of egg laying, and everything else looks fine. I've tried searching on google and can't find anything definitive. In any event, we've kept our flock organic and whatever it might be, want to try an organic fix first. Any thoughts???
