Exactly, there's laws in place that already prohibit running a business out of a home. Specific business types and activities apply, for instance, you cannot start a farm unless it has been zoned accordingly. In addition some cities have limits on what type, and how many animals you keep on premises. On the contrary, it is typically acceptable to have a garden and sell your crop or have a chicken and sell it's eggs (say, at a farmers market).
That's the way you're going to go with it? Why don't you try it. You'll find that those issues are actually already handled by local laws in most places.
