Just a bit of an update. I've gotten two rat racks and have a few litters on the ground. So it's enough to breed for what we need for our own collection, but not enough to sell extras (much less start a business), so we are working on getting a few more racks built and we've started on mice and dubia. I have a few people who have said they'd buy from me so I'm hoping this takes off. Thanks for all the responses.
