Well I have my first ever baby chicks.. I hatched them out over the last 4 days. The newest ones hatched last night. They were fine when they hatched but now tonight I noticed they have eyes that are sticking closed. Not gunky. No discharge or anything. There eyes look clear.... I took a clean towel and doted a little water on & they opened them right up... Now 2 hours later a few chicks have 1 eye closed... Other then the eyes they look & act healthy... What's going on?
