holy moly, dang if I know.
Hmmmmmm. I started breeding mice, because my local mouse breeder went out of business. Then, what the heck I may as well produce more then I need, so I started selling them. Now we produce more then we need and sell them.
I did the same with crickets, only I only produce what I need.
So, if I divide it out, about 300 females produces all we need. That includes my son, hes in San Diego today, I am caring for his turtles, so I am getting the idea, he uses a lot more then hes been letting on to.
That many females takes about two hours a week. The crickets take about an hour and a half a week as well.(for the monitors, turtles and snakes)
I had the mice cages already, I bought them 35 years ago. We live in the country and our property is zoned urban ranch. I also had the out buildings. I would never and I mean ever, never ever breed rodents anywhere near my house.
Oh by the way, we have reduced the number of monitors, but mostly the smaller ones. Why do you ask? Cheers FR
