State guide; According to this, Florida does also have the 1,000 bird exemption. It did when I lived there, and this is more recent. It reads as if the above quoted regulations are to fill the gap between 1000 birds and Tyson.

See my post above in this thread. FL does have a limited poultry license, its $110 per year - but it only allows you to raise and sell livestock. If you are selling your poultry or eggs as a foodstuff offsite, many additional requirements come into play, more licensing, and much greater expense. Originally, it seems to have been intended that the usual licensing for food service operations would be waived for small farmers selling on site, but more recent guidance from the state suggests that's no longer the case.
