It takes a while after their eyes are open before they're ready to be weaned...it's when they completely stop nursing, & eating regular food. And I separate the mom when she's about to have another litter too...it will be obvious.
NO WHEELS in with breeding mice....the moms get "addicted" to it & will run even with babies nursing, they go flying & get injured. Mice have very little "common sense"!
Mice WILL KILL babies that are in competition with another litter...that's another reason to keep either 1:1 or 1:2 mice together at most. You need to pay attention to PREVENT. Pinkies cannot complete with fuzzies anyway, they'll starve...they aren't strong enough to get fed...that's one reason the moms kill some babies.
Mom mice get prego again with the next litter while nursing the first one...it's not rare for the male to jump them right after they have their babies, so they'll be breeding one litter after another, but if you try to leave "vacations" between litters, they usually don't do as well or quit altogether.
ASF = African soft furred rodents...hard to breed as far as I know, BPs usually love them but may not be available where you are.
Mouse chow- lab blocks (for breeding!) are best fed overhead (lab cages) so they aren't crapped on. Using Mazuri brand currently-
