So our chicken has had a swollen eye for about 3 weeks now. It doesn't seem to affecting her behavior at all. She is eating, laying, and acting completely normal. There's no discharge or smell, and it's only one eye. No other chickens in our flock have shown similar symptoms at all. We have been treating her on and off with VetRX, but we haven't seen much improvement. I'm attaching a picture. I'm hoping someone has an idea as to what it is and how we might be able to address it. Thanks.
