I have been looking for what this could be, but I must be the worst person on the planet for figuring out 'search' words. Problem: I noticed one hen today with the tissue all around her eye was swollen. One eye was dilated and the other constricted. So, then I started looking the rest of them in the eyes...some have it, some do not. But only one has wonky dilations. There is no discharge from any thing. Nothing else is swollen. They seem in good spirits. They have been molting heavily, but we were commenting today how well they are all feathering in again. No eggs lately, I figured it was the molt. I was planning on wazine-ing tomorrow... should I now wait? Allergies? something serious? Do I run out to the chicken pharmacy and buy him out?
