My rooster had a swollen eye, not nearly this bad, but I treated it by rinsing with a saline eye wash and applying neosporin twice a day. I was using an rx ointment that I had, but it didn't work as well as the neosporin. I'm not sure he can see out of the one eye, but it healed fine. I wasted about 4 good days trying to use the rx, and I saw dramatic results with the neosporin in only 2.
