I have a hen that is almost fully recovered from a raccoon injury a few months ago. Her skin has healed over and she is walking fine now. I don't think this ^ has anything to do with it but I thought I'd add it just in case This morning I went to check on her and her right eye was closed, but her left one was fine. I opened it myself and it looked fine, but it closed right after I was through looking at it. I thought maybe it was just dry or something got in it so I left thinking nothing of it. Just a few hours ago I checked on her again and her eye was still closed and It wouldn't open even if I tried to open it. I just looked at it again (its 11:48 pm) and its still the same. She is acting fine though. If someone can help please do!
