When I candled last night, I saw 2 of my EE eggs are REALLY porous, and don't look fertile. The other 5 have normal shells and look like they're right on target for day 3-4. I did a search on here for porous egg posts, and I read that a lot of people have had them hatch. How long should I leave them in to be sure of development? I don't want an egg bomb going off on the others.
