I had a chicken start with bubbly eyes last Wednesday. We started Tylan 50 Thursday on all 7 chickens. By Thursday evening 3 of the chickens had bubbly eye. By Friday 2 of the chickens no longer had bubbly eye except the first chicken that started it all. Now all the chickens are healthy again except the chicken who started it all. That chicken then ended up with an infection in both eyes. The drainage is now green. It does not have an odor but it has the eyes swollen shut and and very sore. She is not sneezing or having trouble breathing and when I can get her eyes cleaned out enough to open them she is active like normal and will eat and drink. Problem is I can't keep them cleaned out which means she can't see. Saturday I started putting neosporin on her eyes and I thought that was helping but Sunday night she was as bad as she was before. I am thinking it is time to cull her. I keep thinking though that if I hold out another day she will turn around. Any advice?
