OK, so I need a little help. I just picked up my shipped eggs from my SIL's house. She picked them up for me at the PO. I got them home and checked the eggs for cracks, and the aircells. I couldn't make out an aircell in any of the eggs, but I think i've read that sometimes it takes a while to be visible. The last (and first) shipped eggs I ordered you could see the aircells, and they were all bad. So anyway, SIL had the box sitting on her counter. They were shipped in the carton and when I removed them I saw SIL had them properly. So I took them out and placed them on my desk to continue to set pointy side down in the carton. How long do I need to leave them (considering they've been setting properly since about 10 am) before I put them under my broody? I know night is best, but I don't know that they've been setting long enough to put them under her tonight, so should I wait till tomorrow night? And the fact that I can't see the aircell, is that better than seeing a broken one?
