Let me start by saying Im a horse person, so my descriptions reflect my knowledge there and the only way I know to describe what is wrong. I am new to chickens, but I am having a blast. Two of my chickens- a hen and my roo have what feels like the crusty stuff horses who have rainrot get. Its at the base of their feathers. IS this what molting does? Does the feather get kinda crusty at the base and then falls off? Or is it fungus like when the horses get it on their bodies? Its only in a few spots And the roo has lost a lot of feathers on his bum and looks kinda like he has what I would call "foal scours skin"... the skin looks raw and mottled. He doesn't seem sore, and there isn't crusted manure on his bum, but he's lost all the hair. He's still eating and healthy and none of the other chickens have anything like it So... are my chickens starting to molt and since I've never seen it I am being irrational? Or is something going on?
