Eggs set Today 5/12: Loose Air Sacs

[Griffin Nest]

I had 11 eggs shipped, and 3 were cracked and had completely detached air sacs, so i threw away 2 of the worst ones. I kept the 3rd one and sealed its cracks with nail polish.
5 other eggs, however, have loose air sacs. Not as loose at the other 3, but they are a little bit loose. Will they eventually grow to the point where it doesnt matter???
Also, in 2 of my eggs, I don't know where the air sac is at ALL. It this okay?
Thanks

This is my 4th time with shipped eggs. (I actually do better with shipped eggs than local eggs.)

I have found that in some of MY eggs, until around day 3, I can't see the air cell...

that's weird

at least there IS an air sac and it will grow
