My Cockerel is about 2 years old and is rather poorly looking. He is a white pekin that has had this condition for about 8 months and he has got progressively worse. His co-ordination is completely out when drinking he will miss the water altogether, same with feeding (we have to feed him from a container held to his head). He will walk into things, squint when looking at me and just be rather clumsy. He will extend his neck from one side to another in some kind of fit. He doesn't scratch in the dirt like the hens do. His wattles and comb have gotten considerably smaller, so much so that one of our hens has grown a longer comb than him and now acts like the alpha bird. Suggestions?
