I don't think that's a situation that really correlates to experimentation though? Most of your eggs are going to be laid the right side up and if they aren't chances are the egg will naturally compensate for the issue itself and will make it to full term so long as it doesn't end up getting flipped again. If the egg isn't able to compensate on its own and the breeder noticed this and flips it the right side up to prevent it from dying then that's just intervention.
There's also a lot of factors that can effect an egg suddenly dying, a lot of factors that would probably only be apparent on the genetic level, so I don't know if I'd consider that explanation a catchall.
