I have a fairly large easter egger rooster, but I have a lot of chickens coming into the flock soon, so I went and bought a mixed rooster. He's almost the same size as the egger. It's been a few days now and I've let him stay in the coop, separated from the others, the past few days. I was told to let the roosters fight for dominance. I let them fight a few minutes but my egger has alot of blood in his eye and I feel really guilty. Should I let them fight for dominance? Should I be concerned with his eye? I can still see his pupil but it looks really red. What should I do?
