I don't mean to hijack the thread but we think two of our female mice are pregnant. In both tubs there are two females and a male.

Tub 1 has one pregnant mouse. Tub 2 also has one pregnant mouse.
Should we just take the males out and leave all the females in their respective tubs together?

We are planning on providing more nesting materials and taking out any toys that might be harmful or get in the way but I didn't know that removing the females to their own enclosure wasn't recommended until now.
