I've been seeing some poop stuck(I know it's Pasty Butt) to the butt feathers of my chicks. It's small enough to pick off with my fingers but sometimes I pull a few feathers off, will these grow back when they feather in? One of them has a partially bald area around its poop hole. Could this be from pecking or removing poop? I've seen a few other chicks try to get the poop off of their feathers too as if it's irritating them. Is this normal? Should I wet their bottoms down before removing the poop?
