You had problems breeding white mice? Man, when I used to breed them, I couldn't get them to stop, every other day they'd be poppin out left and right, it was nuts. I never tried with the colored ones though. Have you tried multiple times or just with a certain "set"? I never paid attention to their temps or anything, just clean bedding, water, and food. At this place I used to work, that was all they bred was white mice, but theirs were "special" they had ones with special hormones in them. I just bred regular ones, and had no problem.
