My hen has a very swollen eye. Any thoughts on the cause?? She’s behaving normally and doesn’t have any other respiratory symptoms. Flushed with saline. Do I have to have a prescription to do antibiotics?? Please advise!! We’ve had backyard chickens for almost 5 years and never run into this. She is 1 of 5 new hens we have had for about 3.5 months. None of the others have symptoms.
