We have a rooster who just got into a scuffle with some other chicken in his coop a day or two ago. This isn't that unusual, and he didn't have any obvious wounds, so I left him alone until today. I got a look at him this morning, and his left eye is now slightly milky (like it's covered in a film) and a little sunken. He has some discharge from it, and I think I saw some pus inside the eyeball itself, too. He doesn't seem to be able to see anything from this eye. He doesn't react when we wave our hands or move anything on that side of his head. His other eye is fine, so he's able to get around, and he's acting healthy and normal. Has anybody dealt with this sort of thing before? Thanks!
