My favorite rooster was injured 2 days ago. He never came back to the coup that night and I found him the next morning sitting in the woods, not moving. Both eyes were shut and one badly swollen. Not sure if a predator got him or one of my other two younger roos. I have him confined now, have flushed his eyes and comb with a sterile saline solution and put gentamicin sulfate drops in both eyes. He opened one eye yesterday, but I don't think he can see that well. He's walking around and crowing but has no interest in food or water. Any suggestions to get him to eat and drink? Thank you!!
