Going on vacation, how do I move my eggs with out hurting them?

[SilkieGirl 1]

I am trying to hatch a goose egg and two silkies and it seems to be going great! Then i have learned that we are going on a short vacation but the trip down is long, I have no one to turn the eggs for me and I was thinking that I could put them in a box with a lot of protection so they don't turn all around. (I have a small portable incubator)

The embryos are possibly half way grown because I have seen blood vessels, I just need some advice to move them with out hurting them. Thanks!
