My roo Brownie got attacked by a fox a week ago and cannot stand on it or even keep his balance. I brought him inside and made a chicken sling for him, and his neck was also hurt. BUT, it is better now, and he is able to keep it up. Just not high enough to crow like a real roo. It is more like a gurgle. He tries so hard to stand up to crow challenge! I am concerned that it may be broken. Should i start PT? He can move it, just not put any weight on it. What should i do?
