Oh, I absolutely agree that I had a great hatch.  Here's the statistics:
won a 9+ egg auction.  
Got 12 eggs in the mail (in December, traveling over 2000 miles, during the busiest mailing week of the year. Got to my post office in 48 hours, but mail carrier drove around with them all day and then took them back to post office, never bothering to deliver them, so I got them 72 hours later).
2 started oozing right away, and terrible air sacs so I tossed them the first day.
3 were cooked in the neighbor's malfunctioning incubator around 4-5 days along, so I don't know if they were developing or not.
7 made it to lockdown, though all of the had kind of malformed air sacs.
6 hatched and are healthy.
I would say it was a 67% success rate. (I took the 3 cooked eggs out of the equation, since that was completely unrelated to the seller or shipping or incubating with my incubator) 
It is far beyond my expectations, given the journey.
