I have a big white turkey, Not sure the breed but I thought it was a heritage, but have lately been wondering that point. Anyway, He acts like he is drunk, cant seem to stand still. walks forward but when he stops he takes a few steps backward and then sits, he dosent seem to be able to keep his balance and tonight couldnt get up on the roost. My other turkeys guineas ducks and chickens are all alright, Just him, and there are no other symptoms that I can tell. What is going on with him?
