With the conditions that you state, I doubt your business venture will be profitable. You would probably be better off selling these 'organic' rats as pets instead of feeders.

But hey, what do I know.

If I were in your shoes and had a new idea to get a business going, I would do a quick little business plan and an financial breakdown of the space, time and resources that will need to be put into the business. Then make a decision.

Just wondering.....What are you expecting to sell 25 'organic' rats for?
