They are going to start generating a lot of dust so you should plan for that. If possible, you'll want them out of your house or at least out of the main living spaces. If they have to stay in the house, some people put them in a small bathroom that they can easily clean later.
Do you have a covered back porch, or a basement, or a shed, or a garage where you can put them until your can move them to their permanent home? You'll want to keep them out of drafts with the heat lamp on them for a few more weeks and also be sure they are safe from predators.
