My experiences raising feeders have been positive and negative. This is my third spring having mice, and for the third year in a row I'm experiencing a sudden die-out of mice. Happens in the fall too. I think part of it is that there are certain peak times where I end up re-establishing my breeding groups, and six months later, those are the ones that start to die.
I raise enough mice to sell to petstores and local herpers to pay for their upkeep and food. (if you don't count the ten hours a week I spend caring for them). If you count the amount of mice I need on a weekly basis (40 snakes from a Jungle Carpet Python down to some December hatchling colubrids) then it is very profitable to raise them.
I started raising rats in August once we had an outdoor shed to move the rodentia into. Found they were quite lucrative, as I get five times as much for an adult rat as for an adult mouse.
Now I'm raising Gerbils too... thought those would be a good thing to raise for the Ball Pythons that were picky feeders. (made the mistake of buying WC balls).... by the time I had gerbil babies, the balls were all eating mice, so no need to make them regress to gerbils. So now I have two breeding groups of gerbils, 9 babies from the first two litters, and 11 babies from the two second litters, and the petstores aren't buying. Bout to find out if any other Ball Python people out there need some frozen feeders. But dang are they cute.
Anywya, I'm rambling. I like my critters, scaley and furry.
