One of my favorite hens April Opal has been a bit loggie for the past couple of days and this morning she was laying on her side in the chicken house but got up when I went in but her face looks to be puffed up under her eye and it is obvious that she is sick. Didnt want to come out of the house with the rest of the hens when I opened the door and now is sitting in the nest box just looking miserable. Eye is not closed up just face is puffed up right by her beak. No evidence of breathing funny at least not yet and no evidence of her being pecked. Any help would be greatly appreciated as I have 7 other hens who share her space at night and dont want them to get sick too if its something catching. It has been raining here for last 4 days straight and all chickens are not very happy about that but no one else seems sick or off.
