Speaking of shipped eggs, I wonder has anyone studied the effects of different shipping methods on eggs? I imagine eggs placed on a plane for cross country shipment would be less viable due to the pressure changes, temperature changes, etc. I had eggs shipped to me from in-state, about 4 hours away by car, and it still took 2 days Priority Mail. However, odds are they never left the ground and I think they did very well, 8 out of 14 (and two more probably would have made it if I had been awake to help them out).
