This is how I did it and it worked great for me:
Purina 5001 Rodent Diet
1x5 adults per tub
Pulled females once gravid and set them up in their own kitty litter pan
Rotated females through males
Usually housed around 12 - 15 weaned / smalls per tub until they were feed off
Housed in garage, so they did not breed well in the winter or summer
Used gravity fed water system
Pine Pellets
Hope this helps.
