Actually I have 2 questions. I candled my eggs tonight and 1 I can't find an air sac and am thinking it is a dud but it is a darker egg so maybe I can't see things. But the other egg same color I can see so maybe I will wait a couple more days and decide then. Guess there was no question on that one but my next question is one has veining but the air sac is on the side of the egg. Not sure how that happened, all eggs have been big end up since I got them. Is that egg ok or will it not be able to hatch?
