It is day 5 of incubation and my hen is sitting on 2 eggs, while I was candling today I noticed one had a hairlike ( ? ) crack. I was wondering if you could put nail polish on it and if it would still hatch.? Also, would the egg be ok if I wait till tomorrow to do it because I dont wanna disturb her anymore then I have to or have her crack the egg even more.. I was just gonna wait for her to jump off the nest to do her business. Im really nervous and scared the two eggs wont hatch.. i guess its daddy jitters because this feeling always happens when I hatch eggs, but this is my first crack on an egg. Just need answers thanks.!!
