I have a Wyandotte roo who is not eating, drinking, or standing. It looks as if he might have pulled a muscle maybe? Or he might have eaten something that he wasn't supposed to? Anyways, he has been like this for a few days and I'm not sure that he is going to make it. I mean, it doesn't look like he's sick but even if he isn't he still hasn't been drinking or eating. He was off-balance when he was standing a few days ago and now he just lays on one side. Is there something I can do to help him?
