Hi!
It's do-able. I held some partially incubated duck (??) eggs for longer than that with hot water bottles after I got them (no telling how long they'd been w/out heat before I got them --- the eggs were in a box) and then more hot water bottles for the trip home.
They're still growing.
It's not something I would recommend, tho. My situation was unplanned and emergency status.
If I'd know I was going to be gifted with strange unidentified duck eggs, I would have made arrangements.
Geez, there are easier ways to entertain
Good luck!
If you get the bator to travel and hatch, your technique would be useful in schools and many other places where folks would get a kick from seeing chicks hatch, but don't have the time/patience to wait.
What will happen to the eggs if they don't go with you? I guess they are already set and growing and will hatch when you are away?
Unless you have a keen bator-sitter, then you HAVE to drag them along.
Sorry, I'm a little slow sometimes, but 'taking the incubator' --- regardless of the outcome, is the only option.
Again good luck,
