People who have 1 pet mouse or maybe 2 in a cage, I thought you wanted to be a feeder breeder
When you will have 1.3 to 1.4 + babies (anywhere from 18/24 to 36/48) it will be a different story
Again you are complicating things when it's not all that complicated and proven methods have been around for a long time. You get your info from pet owner forums and show breeders forums and that will not get you far those people do not have business in mind, cost efficiency or practicability.
