I must say it is common practice around here to use a tight compact box for shipping eggs. Jen is quite correct about stacking in trucks and crushing. All the extra packing in the world can't save eggs from jarring and bouncing or xrays etc. The only thing extra packing does is help prevent cracked shells if the box is really mauled by the post office.
With a dropped or mishandled box he same shaking force is applied to the yolk sac inside the egg no matter how much packing is used. The sudden shock of decelleration is identical. F=M x A applied here will tell you all you need to know.
