So I've candled my eggs that I got in the mail and I don't see any veins at all after 5 days. I should be seeing something by now, right? One egg has a big ole air cell. I think I can see the yolk just rolling around in some of them. Isn't it supposed to be kinda stuck in one place by now? Should I just start her over on some other eggs this evening? My eggs took 4 days to arrive, even though they were shipped by priority mail.
