Couple things to think about:
Some hens don't care where they're moved to. They see the lovely eggs in the new spot, plop down and make themselves at home. I love it when they do that.
Some, however, are more particular. I have one hen that requires the cat crate until hatch time if I have to take her out of the nest box.
If I leave them with the flock, their nest box is 100% blocked off with hardware cloth frames to make sure the others can't jump in and irritate her, potentially resulting in broken eggs.
That approach (and a smaller crate too) requires that you develop a routine- let her out once a day- I usually have to lift them off so they'll go eat, drink and poo - I stand guard over her nest while she's doing her thing- nosy hens can plant themselves on her nest while she's off eating, causing (again) a potential for broken eggs.
If she panics when you move her- consider the new area's size issue. Some prefer a very homey closed in space, like a cat crate. If she stands there looking dumbstruck instead of settling in on the new nest, playing with the space could save the situation. Others will love being in our huge dog crate, building their nest in one area and the food/water over there etc.
Either way: I would leave her with her commandeered eggs until her situation is settled. The shipped eggs should be left to rest for 12-24 hrs anyhow, so things should be sorted by then. If she's fussy about you taking her infertile eggs to give her new ones, do it at night.
If she's friendly enough, I like to give them their eggs 2 at a time so they can tuck them (quite professionally) right where they want them. Some hens are too vile as broodies to go with this method- in that case, at night is the way to go. Also consider marking your fertile eggs to avoid any potential confusion. =)
