I'm afraid of doing harem breeding because I don't want to be overrun with feeders and I want to be able to make sure the females get a break between litters so she is recovered enough for her next.

Would it be best to move the male in with the females? or move the female in with the male? I think what we were going to do is have 3 male tubs and rotate the females in. As soon as they have mated, move them into the maturnity tubs, and once they've weaned the babies, move them into a vacation tub. I dunno, I've never bred mice. We also wanted to do a trial breeding before getting all our breeders, so we have an idea of how things should go when we have the other breeders.
