Here's what we did... There is only one pet store in our town, and the owner breeds his own mice. We bought 6 females from him. Then we drove 45 minutes to the nearest Petco and bought 2 males. Then we made two 1.3 colonies. All 5 females are bred (1 died) and the 2 males have since been fed off. When the babies reach 2-months-old I will separate the entire colony into male and female groups. Then they will ALL be fed off. Next year I'll repeat this process. There may be an easier way, but I am 100% sure that my mice are not inbred, and I think that makes for healthier mice. JMO
