Hi folks, need help with my 1 1/2 year old Easter Egger roo please. Did a routine butt check today and discovered his vent is dry, red, and inflamed. No evidence of lice or any other parasites. Plenty of fluffy feathers except right at the vent, where he is clearly picking at them. His behavior is completely normal, he eats, mates, crows, runs from my Jersey Giant rooster, and aside from some recent minor comb injuries from the big roo, he has no other symptoms at all. He smells fine too. Unknown what his feces is like, I have not yet isolated him. Can anyone tell me what's going on? Thanks!
