I have about 9 coturnix quail that we got in August that all live in a hutch together in our backyard. Today when my fiance and I opened the hutch to grab some eggs, we noticed this little lady's eye. It seems to me very obviously infected, though I don't see any puss or discharge. I'm wondering if it's possible that she just got something in her eye that irritated it and caused this to happen, or if someone who is more experienced can tell me if it looks more serious? So far we've bought saline solution, and found an antimicrobial eye wash at a pet store that we may try. We also have added a dash of apple cider vinegar to their waterer - not assuming it will cure anything, but just for extra healthy benefits.
