i think you can count states between you & the shipper
if it a large number 6, 8, 10 a good hatch will be tough
only a couple states away you may get a bunch to hatch out
The key factor is the distance between the airport, the service center and your house and the same on the receiving end. The total miles by truck in other words. The more the box bounces in shipment, the worst they are packed, the lower the hatch rate. Sadly there is way too much blame the USPS and not consider the packing. Nearly everyone that has constantly bad shipping results packs the eggs very poorly.
Miles in the air do not hurt the eggs.
I had eggs flown from Spain to San Francisco and had 12 of 15 hatch. That would equal a lot of States! The eggs were flown in carry on luggage so they did not bounce.
