What can cause air cells to be not positioned correctly?

[chickenmomma16]

I just candled my eggs on day 7, tossed the blanks and I had a few that had improperly positioned air cells (positioned more to the side then the top) They were my eggs collected daily, and stored air cell up in an egg try for no more then a week. Never seen this issue before. Anyone else?

I've just had 2 with funky air cells hatch yesterday
As far as I'm aware as long as the air cell is attached it is fine.

I had a few with funky air cells, I have never ran into this before and it’s weird they were all in this batch. They are on day 8 so hopefully they will hatch okay.
