My daughter noticed about three days ago that one of our Polish chicks had a crusty, sandy eye. I cleaned it by carefully pulling off the crust and sand and put antibiotic cream on it and let it go. It improved slighty, but it is still red, a bit swollen and kind of crusty. It has a white film over it unless I flush it out. It does not stink at all so most likely it is not Croyza, right? It has a lot of energy, eating and drinking fine. I might have noticed one sneeze, but I am not sure. (It was windy outside when I was watching it.) I have removed it from the rest of the flock, but so far this whole day, no coughing or sneezing. It is very unhappy being away from it's friends, so I need to know if I should remain concerned. The rest of the chickens are bright eyes with no puss or weepy signs at all. What to do? Edit to Add: There is a small possibility that it might have gotten pecked. There is a small scab above it's eye...but that could be from me removing the crust from the eye. Am I grasping at straws here?
