I noticed one of my ewes had a bit of a weepy eye the other day. I can't really see anything wrong, thought perhaps she'd gotten some hay there or bumped herself. I was gone all day today, so didn't get a good look at it (dark out there!), but doesn't really look much better. No swelling or pus, just weepy. She's still eating fine and behaving normally. Color in gums, etc., looked fine yesterday. Anything I should be concerned about or looking for?
