Alright, following player suggestion, we have two new things, interrelated.
Once you've researched hunting, Ranching becomes available.
Once you've researched Ranching, you can build a ranch.
Protip: Ranch will do better if adjacent to an agricultural zone.
Farms, wells, and Ranches will now produce creds instead of food if your people don't eat that kind of thing. So huskies with an agri zone are just making trade goods, because they don't eat carrots. Same would be true if we made some herbivore rabbits and they owned an animal ranch. They're not going to eat the cows, but they can sell the milk, meat, and leather to others.
