I was talking to someone up here in Alaska about buying hatching eggs from the lower 48 States and she said she has a poor hatch rate with many detached (??) air cells. Everything is air-freighted up here. I was wondering if it was a problem with the decompression of high altitude. Which leads me to the question...would it be worth the trouble to try to use an air tight shipping container?
There was a thread about the changing of altitude a while ago, I think it was a thread by BUSTER. he was testing eggs that came from a different altitude. He also tested various degrees of humidity when hatching, I believe the best hatches were from different humidity levels that are generally advised. You can try search by the user name Buster and see if you can find anything - I didn't follow it much as I wasn't really into hatching more eggs at that time.
