I have a little bantam rooster that my daughter accidentally let out of there pen today “didn’t know till hours later when returned home” and our big roosters chasing him. I’m not sure if he lost his eye or just a deep injury. There a little funk of stuff on eyelid , I’m assuming it’s part of his “corna” or whatever it’s called on outter eyeWhat can I put on it to ease his pain/ and help heal it. Thank you in advance!
