I once got 2 dozen turkey eggs from MHM packed like this, with the foam and cut-outs. There were 4 cracked, but I've often wondered if they may have already been cracked when they were packed. People working in a hatchery, packing hundreds of eggs to ship out may not be as careful as an individual would be.
Anyway, they sent 4 extras, so I still came out with the number ordered, and of the 2 dozen, half hatched. That was my very first shipment of eggs, and I've gotten 5 shipments of eggs from individuals, since then. The turkey eggs in the foam were my highest hatch rate for shipped eggs. So I'd say a big
on that method, and on the individually bubble wrapped, as well.
If you make sure they can't band against each other, are snug in the
center of the box, from
all 6 sides, with non-shifting,
shock-absorbing packing to keep them from moving at all, they should be ok. Don't go overboard with the tape on the bubble wrap, you don't want eggs getting broken by the customer, trying to get all the darned tape off. One or two small strips of ordinary scotch tape, (
not packing tape!!!) to hold the wrap on the eggs themselves.
Somebody suggested folding a bit, sticky side in, on one end of the tape strip when wrapping the eggs, so there's a loose end to grab easily, to remove the tape. I'll be doing that from now on, when I ship eggs.
