Last night when I brought the girls in for the night I noticed one hen was swollen around her left eye. There was no discharge from the eye itself which looked healthy and clear but some clear discharge coming from somewhere closer to the mouth. This morning her eye was completely swollen shut. There was more clear discharge then last night and a small amount of discharge coming from the eye. It seems to be painful for her she is also not leaving the coop now but she is still eating and drinking.
