HELP WITH DEER MOUSE!!!?

I have a deer mouse as a pet in my garage. I hadn't seen her walking around the cage in a long time so I thought she was dead. Turns out she had babies. When I lifted up the log, she ran and scattered the babies around the tank from her. Now she won't go back to the babies. I tried making her cage as open as possible and putting the nest in a little rodent igloo. Tell me if that would work. I have experience with the House Mouse but not AT ALL the Deer Mice (except for like 3 adults that I kept last year)
