I have a silkie who looks like his head has been put on the wrong way; sort of sideways. I first noticed it when the chick was a few days old, and over the past month it seems to have gotten better such that I can hardly see the tilt. So now he is a little over a month old and yesterday when I picked him up his head fell over sideways and he was rotating his neck and head as though trying to get it upright. He can still walk, eat, and drink but occasionally he will sit down and his head will fall over and he will rotate his neck, and he walks with his head tilted sideways. I have felt the neck, but I don't feel any abnormality. Is there anything I can do for him?
