Ok. This has been a super long ongoing process. My lavender Orpington pullet, developed a swollen eye (not hard) overnight about 2 1/2 - 3 months ago. We did research and decided it was probably MG. We gave her Tylan 50 via injectable for 5 days. The swelling went down as well as the redness. She was then acting lethargic. We wormed her and dusted her for mites. She is now less lethargic. BUT.... The swollen eye has returned! This time she has her eye open so I can see it better, and it's hard and chunky yellow goo. It's nasty. What should I do?
