Detached or saddled air cells?

[Hopeful homesteader]

My eggs are coming from my own flock and they are fine when I put them out under the hen but when I candle them at day 7 some have detached air cells. They aren't fully detached but appear somewhat saddled. Is there any way to tell what's causing this and how to prevent it? Out of about 30 eggs I've found 2 like this and they came from different hens so not sure if it's really something to worry about or if this is normal from being under a hen?

Sometimes developing on their sides causes the air sack to slowly move to the side of the egg, but I've found it normally moves back to normal a few days before hatching.

I have one broody duck who had all her eggs get wonky air cells and she laid all the eggs herself and they never left her nest.
No idea why but was told maybe she is turning them a little crazy
I myself have hatched well over 60 of her eggs and never had one go wonky and did both upright turner at the schools and by hand on the side at home
My new broody has perfect air cells
So could be how she is handling them
