Will air sac move around if you move the egg?

[Hangin Wit My Peeps]

I recently candled my eggs and one of the air sacs would move around...if I turned the egg upside down it would stay at the top of the egg. Is this normal or is the air sac suppose to stay put? Prob a stupid question but I have NO clue! lol I had to throw that eggs because it was clear.

Thats called Tremulous Air Cell..The air cell should be stationary at the large end of the egg

Thanks for that info...If it does move does that mean that the chicks will not survive? Or even grown?

I have hatched them before, but the odds of them hatching are not that good, And I question the quaility of the chick because you have to help them out most of the time. Now when I recieve shipped eggs and the air cells are shakey, I just throw them out..Not to say it only happens in shipped eggs, eggs that are laid from the roost or handled ruff can have lose air cells also
