We have been having trouble with bumblefoot on our 5 month old rooster. We've been under vet care for that. My problem stems from something else. He has been lame for over a week now. He poops, I clean it up when I smell him. Now he makes a wierd noise, moves his feet and brings his head down when he poops. And he doesn't seem to be pooping much. What I do clean is mostly liquidy. I think he's constipated? Or has a diaper rash? The poop shoot area apears red and irritated. There's nothing else obvious I can see that would cause him pain. Thoughts?
