I would watch them for the first week. Once I had 3 mothers have babies all at once. 3 separate nests in 3 different corners. But then one mother started stealing babies from other nests and then all the moms started tug-o-waring on babies. I lost a total of 10 pups because they were all torn up. It was inhumane to let them live, so I fed them to my ferrets.

But if there aren't any issues like that, then its fine to leave them together. Most moms will share duties caring for all the pups once they're all sharing a nest.
