I received some shipped eggs that a few with aircells were totally destroyed and sloshing about (they were very well package but we know how it goes with shipping). I put them in the bator anyway and surprise surprise they developed and are still alive on day 16. The air space however is still a mess and goes up and down on both sides of the eggs. I kept them upright since they got here. It should be an interesting hatch. The air cell dips down like this on the opposite side also. I have 3 like this. It is day 16.
