About a week ago I had some younger chickens (about 8 wks) afflicted by some upper respiratory disease. Symptoms in the worst case were watery swollen eyes, sneezing and wheezing, lethargy and not eating. Not all the chickens came down with it, but I treated them all. They all seem to be over it, but the chicken that had it the worst still has an eye swollen shut. Every day I try my best to clean and open it, irrigate with saline, and apply Neosporin. The skin around the eye seems so thick I'm not sure if it will ever go back to normal. Is the eye a lost cause at this point? Is it better to keep messing with it or should I just leave it alone? I'm not so much worried about blindness, she's been getting by fine with her one good eye, but I'm concerned the eye will get infected.
