What’s going on with this air cell?

I have 22 shipped eggs in the incubator and 4 haven’t developed at all ? Not fertile and then I have this one. What’s going on with the air sac? Any chance it will successfully hatch?

since they were shipped I will say that it is a saddle shaped air cell. It is a strange position but one hard jolt would do that I suppose. The air cell is always bobbing away in the egg and is held in place by the membrane, with a large jolt the air cell can dislodge the membrane attached to the shell and squeeze itself into a new cavity it has formed. It shouldn't affect the embrio too much. I am having to deal with a completely detached air cell in 2 of mine, that is more troublesome, their air cell freely floats all over the egg. Yours luckily didn't receive such a big knock

Thank you. This is my first try with shipped eggs and I was thinking it was some form of saddle air cell but didn’t look much like the pictures I saw in the articles.

I second what was said above. I’ve had shipped eggs with air cells that look pretty close to that and they’ve hatched successfully.
