Two of my roosters got into a fight tonight. We walked into the coop to see the dominant rooster cornered by the other. We separated them and found that the one wasn't hurt at all, but the dominant one seems to be missing his left eye. There is a good amount of blood on his face, but I don't see any open wounds. His right earlobe is black and purple and swollen, and I think his head in general is swollen up. Is there anything I can do for him? Would pictures help? He doesn't seem to be hurt anywhere else.
