Some of us do leave the Males with the nursing females that they impregnated. I have had no bad experiences in doing so (but again when they males get really big, I dispatch them and put in a younger male (fat males tend to get lazy). I also leave several female pups in with the colony as I take out the weaners so that they can grow..as they grow and the adults get old and die or dispatched, there is always a fresh supply of females for the males to impregnate.
What I suggest is to look over all the options/suggestions given, and find something that works for you. My way may not be everyone's way, but it works for me and I am always having to freeze my surplus of weanlings, small rats, med, big and huge rats.
I feed my rats good, I am not prone to keeping non-producing or problem rats on the payroll.![]()
