Oh god mice are awful! I had only 2 tubs of them with a total of 7 mice and they were stinking me out of the house! I have a breeding rack with 12 mortar tubs FULL of rats and 4 large colonies of ASF's and all of them combined didnt stink as bad as the few mice I had.
I would definately breed some ASF's. They have very little odor, have huge litters and do well on lab blocks and a little alfalfa once in awhile. If you ever get too many there are always people looking for them that you can sell to. Just be sure you keep up with the rodent laws in your area and be aware of any changes that may happen. They are illegal in some states.
