Crystal,
The easy way would be to leave them in the present box and give them foundation frames to build on. Then later on you can move this box above a queen excluder and eventually remove it.
Another way would be to place the box up side down and push all of the frames out of the box. Then you can cut the comb out, one piece at a time.
Do not do this until it warms up quite a bit.
I would like let it Bee and let it grow. Eventually you can move this box up to the top and they will replace the brood with honey and you can harvest it.
