one of my roos got attacked by a dog. only damage I can find is a ripped comb. the back third of it it turning purple black, but the wound does not appear to serious. my concern is that the roo has trouble standing or walking, like his balance is off. he is not eating or drinking since the attack which happened about 24 hrs ago. I kept him in the house overnight & have now put him back with the hens. he is trying to eat, but stops about an inch short of getting the food. not sure what the problem is or what to do at this point. any suggestions would be much appreciated.
