I would think that a stir container like they ship frozen steaks etc in with a cold pack might work if it can get there in two days with USPO.
I have done reverse in cold weather with heat wraps. I see those stir shipping containers in the thrift type stores all the time. Just a thought.
I must have three dozen of those styrofoam containers stacked in the loft of a shed; small, medium and some quite large. I saved them, thinking they would be of some use and I guess they still might.
I can't understand such expense for shipping eggs. Something seems wrong here.
EDIT: If they can ship 25 live chicks for about 20 bucks, a dozen eggs plus container and chill-packs should go for roughly the same price or less.
