I need help in determining what's going on with my 22-week-old Easter Egger. I noticed her eyes seeming runny and goopy last night and this morning one of them is closed and the other is barely open. At times, she has her beak open and doesn't want to leave her roost. Other than those symptoms, I don't notice any others. I'm new to chicken owning and am not sure what to do other than isolate her; Although, I fear its too late for my other two hens as they snuggle closely at night and they're probably already exposed to whatever it is she has. Anyone have any idea what this is and what to do about it?
