I used to breed all of my own rodents for years and I can tell you it's a major PITA, if you don't have the time to keep up with it properly your productivity can go WAY down. Eventually I was spending more time babysitting rodents then I was spending with my snakes. I just got so sick of spending so much of my valuble time cleaning/feeding and watering feeders that I ended up getting rid of most of my rodents and now I just buy frozen. Yes the prices have gotten ridiculous, but I'd rather have the extra time. I do still keep a few colonies of mice for hoppers to feed my babies, and a couple colonies of rats for those stubborn live feeders, but mostly I'm enjoying being a little poorer but with more time on my hands.
