I don't have any pictures available to show how I pack but I can try to explain it as best as possible.
I use old egg cartons but sprinkle some planer shavings on the bottom of each first. Planer shavings are those curly wood chips if anyone doesn't know. I then set the eggs in and add more planer shavings on top. I then shake the carton making sure that nothing moves. If it does, I add more shavings. I wrap each carton with plastic wrap to ensure that the shavings don't leak out of the carton during shipping. Cartons are placed in an oversized box with plenty of balled up newspapers. I also shake this box to ensure that nothing will move or rattle around during shipment.
Everything that I use for shipping can be used again for some purpose and was destined for a landfill. I'm not one of those eco nuts but just found a way to ship some of my garbage in a way that helps both me and my egg buyers.
Egg cartons come from neighbors and friends, planer shavings from my little wood shop, and the newspapers that they send me whether I want them or not. I also get my boxes from the local grocery store that just throws them away anyway.
It's a fairly inexpensive way to ship eggs when everything is recycled. ( except for the eggs)
If you don't have access to planer shavings, you could buy a bag of cheap hamster bedding from the local pet store or farm supply store.
I found that cracked and broken eggs during shipping is largely due to movement of the eggs in the box, packed too tightly, or just the seller doesn't care if thier eggs arrive safe or not.
I have dealt with a seller who didn't care and paid for a bunch of broken eggs. I make it a point to do my best to ship good eggs even if it costs me a bit more for shipping. If profit means more than happy customers, I'm not going to sell eggs anymore.
I sure hope that everyone thinks the same way.
Well, this is my method. I have done well in shipping this way if anyone wants to try it also.
