We live smack in the middle of the city on 8 acres. We raise Nigerian dwarf goats (6 females right now, all pregnant), around 20 hens to feed us and some close friends fresh eggs, 2 Great Pyrenees to keep the coyotes at bay (tried a donkey first but she was useless), and are strongly considering breeding Golden Retrievers.
We have several small raised beds with blueberry bushes, blackberries and we tried grapes but they didn't take. My wife has a whopping 12'x12' garden in the back yard with several small raised beds around the perimeter. She grows a small amount of a lot of stuff, from cantaloupe and watermelon to tomato, cucumber, peppers, potatos, you name it.
We have 5 young kids so she intentionally started small, but we'll be building a house in a few years and plan to enlarge the garden after the house is done and we know where everything will go.
We also have 6 bee hives and growing for fresh, local-as-you-can-get honey (and the bees get us agg exemption - $$$ - on the whole property).
We planted several fruit trees two years ago but they were too far from the house and didn't get taken care of and none took. We'll try that again soon with a better game plan.
The property has a decent pond/tank on it with plenty of catfish and a handful of bass, plus bait fish obviously. I intend to enlarge the pond to triple or more the water volume to grow larger fish (catfish for eating, bigger bass for fun), but I don't know if 'catfish farming' is a thing.
