That's interesting. I just received 14 eggs that were shipped and they were rapped similar to this but they were doubled boxed as well. 13 out of 14 are developing.Bob I don't think you can do any better than this, unless you take them to your friend's yourself.
This fellow sent me egg like THIS, and they arrived in fine shape. I've used the same method, 3000 miles away with success, and had friends ship to me using this method, no breakage.
My boy is a cub scout and every fall the fire company brings a ladder truck over and the boys get to drop an egg off the ladder, packed any way they see fit. My boy uses this way of packing, and never has had a broken egg. From 40' in the air onto concrete.
