I candled and could defanitaly(sp?) see veins in some and others I could not see through at all. I don't want any to explode and make a mess, so I need help in determining if they stay or go? I also noticed that I have 2 eggs thay have a few cracks like they were dropped when laid(don't know how they made it in the incubator without me noticing) and I know for sure that one of them has veins and movement so do I toss it or try my luck? Thanks
