chickenlisa - I'd start it as a new thread. I believe you would get some good responses that way as people would check it out and many have already read this one and think it's done.
Unfortunately, I can't help you at all in shipping eggs. Good luck.

My concern this time of year is the freezing temps in the airplane baggage compartments. Most (maybe all) airlines won't let you ship dogs/cats during these cold temps because of that. I'm assuming that's the case with chickens too?
