I've found that pretty much every bantam egg that's shipped to me ends up with the "wonky air cells" that dip down in places that they shouldn't, and can be clover, kidney, or heart shaped.
I keep the humidity pretty high with those eggs, and they never seem to have any trouble hatching - in fact, the eggs with the wonky air cell tend to be the first to pip!
