.......so I've gotten my first breeding colony of mice. Yay!! I have a 1.3 in a large lab cage. Now.........the quandry..........at least one of the females I got was already pregnant. I have no idea if the male that I got is the daddy or not (the person I bought them from had them all together.)

If I knew he was the daddy, I would feel comfortable leaving him in the tub. But since I'm not sure? Is it a good idea to leave him in, or take him out? Should I instead take her out? I would like to reduce the possibility of them being eaten as much as possible. But, I don't want any fighting upon re-introduction...........

Drat. Any suggestions?

Thanks in advance.
