I have a oe bantam that has a big cyst looking bump under one of her eyes. I treated with tylan for 1 1/2 weeks and then with another antibiotic for 1 1/2 weeks. There is no change. I don't dare to keep her on meds longer, especially if its not helping. Her eye is a little wet looking but not really draining and her nostrils look good. I think it is interfering with her sinuses though because she keeps her mouth open a bit all the time. Any idea what I should try next?
