These eggs any good?

[tarikt]

Hi,
My delivery of eggs just arrived and I am ready to let them acclimate.
But I am running into 3 issues.

N1 I cant find the flat side of the egg. Both sides look identical to me

N2 I also cant find the air sacs when candling. Which means I cant identify the flat side

N3 some of the eggs slight slosh around when handling them

Are these eggs any good?
please help

air sac may be detached. If there's no air sac nothing can develop or survive. Yolker/quitter.
With round eggs like that with sides that you don't know which is which, best way to tell is to candle and where the air cell is is the bottom of the egg.
