I have a chick that is about 11 weeks old. She runs with the other 23 chickens that I have. I went outside today and noticed that she has foamy eyes. I watched for a little while and I didn't see anything else wrong with her. She is running around and eating and I didn't hear any sneezing. What could this be? Also, how do I treat it? Do I need to isolate her from the other chickens? I checked the rest of them and didn't see any other foamy eyes in the group but should I treat them just in case?
