Shipping eggs, big end up, in rolled up bubble wrap tubes, all spaces filled with peanuts just about assures no broken eggs. We shipped and I have received countless boxes of eggs using this method with never a broken egg. Broken eggs isn't the issue and beyond the unnecessary expense of the foam package, it won't likely solve the real enemy of shipped eggs and that is the Post Office.
There is nothing one can do once you drop them off at the PO. They are tumbled on conveyor belts, likely dropped into bins, jostled about in hand carts, trucks, altitude and pressure changes in planes, plunged into freezing temperatures, left in boiling hot summer trucks, and so on ad nauseum. Sometimes it is detached air cells and similar damage but other times the insides are shear scrambled eggs as if someone shook the egg with all their might.
It is an acknowledged crap shoot that good packaging alone cannot solve.
