I noticed one day while feeding my chickens that one of them had torn up feathers under its eye. I examined it and saw a bloody, muddy mess of flesh hanging off. It wasn't to bad. I washed it well, and put some bacterial cream on it. It healed for the most part. I figured my rooster with a limp must've accidently grabbed her face instead of her comb. But today, I noticed where her cut was was very muddy, and I wanted to clean it off because I figured the cut was still healing. I got a closer look and right by her eye it was swollen and puss-y. I have no idea what to do. Please help me! Anyone?
