Davids right they will be fine. Last year another member here Chris Collett had a surprise clutch of eggs, he called me worried that he had no bator. He brought them to me about 30- 40 miles away and i put them in my incubator. He set up his own bator and came back for them several weeks later. They all hatched fine even though they been through multiple car rides without any temp control during travel.

I would takes them out of the bator, move the bator to the new location and then bring eggs. As mentioned they are alot tougher then you might think. Also if the egg box is sealed the temp change should be real gradual. In nature things dont stay perfect like in a bator
