Answer
Hi Dacey

It could be the trauma of the move making her more nervous and bringing the onset of whelp.
 
6 hours seems like a long time, but you need more information.  You don't know what day she is at or if she has had pups before, what she was bred with?

If she's too early then her behavior could be a sign of complication.  You want to make sure she's not straining and pushing without any success.  You want to keep her hydrated, calm, and in an area where she can comfortably and safely whelp her litter.  You want to make sure that her discharge is not black/green and has a foul odor.
