One of my young hens that recently began laying, is walking around with one eyelid closed. There does not seem to be any discharge from the eye or her nostrils. I've seen no signs of respiratory distress. It is possible she scratched the eye. If that is the case, should I be putting some kind of drop in it, or just leave her alone. She is a bit stand-offish. I would only be able to handle her after she goes to sleep. Is there any eye related syndrome that can occur at the onset of egg laying that I should be aware of? When she briefly opens the eye it doesn't appear discolored, but I'm judging from a distance of about three feet. She seems to nap more frequently than a lot of the other birds.
