Oh and I just looked up sexing mice on Google and the space between the gap is very small on our mouse so I would put my money on it being female.

So at this time if we were to start breeding what would we need to get (other than Mazuri food and Aspen bedding)

Should we go ahead and purchase another 2 females and a male along with additional tanks for grow out, male vacation and female vacation? I'm worried about mice chewing out of tubs so would tanks be a better option? Oh and just a tid-bit...The mice would be at my fiance's house (as my grandmother said absolutely no breeding mice at her house) so we are pressed for space at least for a while.
