I have a barred rock hen that has been squinting lately and I really didn't think much of it until yesterday when she wouldn't open them at all. She will open them a little bit when she has to (when she walks around, drinks, eats etc.) but other than that she just sits around with her eyes closed. And she will turn her head to listen so I have no idea what is up with her. She is separated from the rest of the flock now. Any help would be awesome!
