Breeding mice questions

[Snikt228]

Best way would be to just stick them in a dark place, like a closet and just leave them alone. Clean once per week and provide plenty of lab block diet. You can keep a good number of adults on a 10-gallon tank. I usually do(when I have to use tanks) 1 male to 5-6 females. They do great.

So they don't need any kind of day/night cycle? Right now they are in my bedroom which I usually don't go into except for sleep
