I worry about inbreeding though. Won't that affect the health of my colony if I keep breeding related animals? I was always told to introduce fresh blood into the colony to keep it healthy. I ended feeding off some of the females I was holding back. I held back 4. The two does are back in with a male and I am waiting on 1-2 females to pop.

I don't have any racks right now because I just suck at building them. If I had a mouse rack that would make life so much easier. I have started building mouse tubs though. That way I can just stack them on top of each other as I build more. Once I move though I'm going to find someone to build me some rodent racks so I can really build up my colony.

I just did some math and I need 20 adult mice per week. How many females should I have in the breeding colony? And I need 9 rat weans and 8 small rats per week as well.
