We just started keeping chickens this spring. Been getting eggs for a little while now. #1. Just noticed one has "poopy butt". Where did I read what to do for that? #2. But the main thing I want to ask about is a small to larger area just where the tail feathers start on about 4-5 of them that look like someone just plucked several feathers out. Looks like it's red and probably hurts. I first thought they were being pecked on by the others, but I am thinking it might be an illness/disease. Can anyone help me on this? Nita 4679 (a total newby) I hope I'm in the correct section. Tell me if I'm not.
