The other day while putting the chickens up I noticed one of our chickens had a really swollen eye. Since it was night time I didn't do anything but made a note to check on her in the morning. In the morning it was draining a lot. Her whole side was crusty from her wiping it off. I wiped it up and tried to see inside to see if it was injured or something in it. She wouldn't let me touch it so I just put medicine on it and left it. The next day the swelling was down a little bit so I again wiped it clean and this time a large chunk of hard white stuff came out. I put the medicine on again and put her back with the flock. She is eating and drinking fine and no one is really picking on her (no more than the usual peck between girls). She doesn't have any discharge from her nose, no shaking of the head, not acting sick. After 3 days of medicine the swelling has gone down but is not gone. Today she opened her eye and I couldn't see anything but red in there. It looks like there is no eye at all. Here is a pic. The crusty stuff above and below is the medicine. The string of stuff coming out was jelly like and came right off. The white stuff in the corner is like what I got out previously but this one wouldn't come out. Any ideas what's going on? I've searched it and it doesn't sound like anything else I've read.
