Hello- We have a Rhode Island hen that has an eye infection. I've talked to several people who say that it is pus that is covering the eye. She is acting completely normal-eating, drinking, socializing, etc. She just can't see out of that eye at the moment. Now two things: should we remove the pus? If so, what is the best way? We don't want to hurt the hen's eye! Should we buy the Terramycin antibiotic eye ointment at the Tractor Supply store? How often should we apply it to the eye? Thanks so much!
