You can make a profit off 1.3 ASFs, and probably mice or rats as well. I don't see why you couldn't make a profit off producing more.

The trickiest part for small-timers is finding buyers. If you had a 1.3 colony of ASFs with a single reliable repeat customer, you would come out on top pretty soon. You wouldn't make ALOT of money, but you would technically "make it", if your goal is just profit

If your goal is to sell feeders as your only source of income and support, for example, a family with a stay-at-home spouse(no extra income) and 3 kids.. I think not.
