I hatched 4 chicks 3 days ago, some of which were born with some minimal goop and egg shells on their fur, though were still able to fluff up on their own. The next day, I noticed that 2 of them would periodically have one or both eyelids get stuck shut after snoozing. They usually opened on their own, or it would take just a dab of water to unstick them. 2-3 days later, the problem has totally gone away, and their eyes are bright and clear. In researching it, I almost exclusively stumbled upon horrid articles which indicated that this was a serious disease, that I should report to my county ASAP. Now, it appears to be totally better. This was my first time hatching at home. Can more experienced Hatcher’s tell me if this can be normal, or if I should be worried still?
