Hello all, I am planning on trying my hand at rat breeding for food for my collection of snakes, I need 10 per week. From reading the stickie the ideal number is 12 female rats to do that, I'm not really to sure how they get that number. From what I've read on breeding rats it is best to separate all pregnant females meaning I would need 12 tubs just for females on my little rack to do that? I have a small rack that I'm using which has 2 tub levels but I think I can add between 2-3 more levels if needed. Is there any way I can pull off breeding to get the numbers I need with my tub limitation? Lets assume 4-5 tubs.

Can I do less than a 2.12, I have read metalmonkeys site on breeding rats at minimum of 2.2, would this be possible to run and produce enough feeders eventually to sustain my collection?
