Our roo is painfully thin. I noticed he was just kind of quietly sitting in a corner last week and then a few days ago I saw his comb and wattles were bluing. I've placed him beneath a heat lamp but I didn't notice anything other than deep, slow breathing. He has periods where he's not bluing, and tonight I notice a LOT of white poop, and a couple bright green, mixed in with normal poops. He's listless. I don't know what to do for him! He has no symptoms of respiratory infection. I checked here over the weekend and am wondering if it's his heart. He was fine when he was out with his girls (hens) but we removed him because one of the hens was all bloody. He ripped her feathers out regularly. This couldnt' be him giving up because he lost his girls, could it?
