you figure the secret out to throwing 20-30 per litter and keeping them alive and I will be one of your top supporters. That would be doubling to tripling my current output per rat.
However, my rats do not get those types of breaks and a down time of 6-7 months would not pay off. /in seven months, my mothers would have already produced 60+ offspring....some would be in the 80 range.
difference strokes....
