Although I don't ship a lot of eggs, usually only for swaps. What I do is wrap each egg in bubble wrap, then place them inside an egg carton (this works good for bantam eggs) then wrap the carton with bubble wrap. Then pad the shipping box with newspaper all around the egg carton. Just don't make it too tight in the box so there is a little wiggle room. This has worked for me and as far as I know all my eggs have always arrived fine.
