This morning I woke up to find that my 8 month old Orpington cockerel is not doing well at all. Last night he was perfectly fine and had bread, water and food. This morning he is very lethargic. He doesnt want to move from the one corner of the run. His tail is drooped and his comb has white spots near the base. When I picked him up to feel his weight, that seems fine. But when I set him back down he stumbled and held out his wing to regain balance and continued to have trouble with his balance. I am very worried and have no idea what has happened. Any help is greatly appreciated! Thank you!
