Advice- hairline crack in egg

[bordergurl]

Locked down 7 eggs yesterday afternoon. Everything was fine. Last evening I noticed a hairline crack right in the center of Egg # 7 that hadn't been noticeable earlier in the day. What do I do? Leave it, pull it, pull it out of there, wax it and put it back in?

I have one with a hairline crack and one with the pointy end broke (looks like a hen pecked it once).
Both so far are doing great.
If its made it lock down like that why mess with it now...

On day 7 I candled some of mine and dropped on. it cracked pretty big but I just set it back in and watched it to make sure it would not leak. On day 21 a chick hatched out of it! I thought about wax or tape but did nothing and it was fine.

Well that gives me hope! I left it there as today is day 20. I hope it doesn't explode all over the others!
Thanks
