Yes I leave the 1 male with each group of females 100% of the time.
I have 20 colonies of rats. The males have never hurt a baby. I have never found any signs of babies being fought over. 2 years in and I dont see my system changing anytime soon.
I'm feeding 50+ snakes and various amounts of babies at any given time. Never have a shortage of feeders. In fact I have enough extra rats to trade for a few hundred pounds of rat food every month.
