My BSL has had a swollen eye for over two weeks, I had her on Tylan-50, which I wasnt sure if it did anything, but after ten days of treatment, I felt it was too much medicine. The eve never really stopped swelling,but since she is off the swelling seems to be getting worse. Should I try to use terramycin eye ointment? I used some Vetericin, that didnt do diddly. I did lose a pullet to the disease that causes the eye swelling, I also lost a bird before that who just got weak and dropped dead. Is terramycin worth a try?
