Thank you....when i get to look at the eggs again at least I will have an idea...lolGood morning! The air cells will often be off center.. Especially as time goes on. But this one was completely on the side of the egg. It's just so weird. I wouldn't be surprised if they were shipped eggs or if I had bought them. I would just assume that someone left it laying down for a long time. These came from my flock though and I know they were stored correctly. Hmm. Actually, now that I'm thinking about it again.. I DID have an egg that sat out on the counter for awhile... It wasn't supposed to go in the incubator, but maybe someone stuck that egg in there when I wasn't looking. I feel silly for not thinking of that sooner.
