Hope someone can advise on this: Ravioli is a 4 year old cockerel. 2 days ago i noticed he was hunched up and his comb slightly bent. Yesterday i seperated him and gave him high potency soluable vitamins as well as tuna cat food with some wormer on (to be on the safe side). He ate all his food but today his comb is bent right over and he is looking a bit sorry for himself. He feels like he has lost a little weight but he is not too thin and today hes not really interested in the cat food. Are these signs of a problem anyone recognises?
