Thank you for the welcome!
My fiancée has some experience in breeding fancy mice, but we'd be more likely to try breeding fat-tailed gerbils.¹ Still, I'd consider breeding mice if I felt assured that I could place the pups in good homes.
I would of course only try to house two males together if they were brothers. (When I was a kid, I had a couple of mice (Bob and Ray) who were brothers and were always very dear one to another. Probably a significant part of that was in that I never separated them for more than a few minutes.)
¹ Not a legal option right now, as I live in California, where gerbils of all varieties are illegal.
