Loving the herd life
Edit to add: To the best of my knowledge, pigs are happier when you have at least two, and three acres should be enough land. We have five acres, but the pig field is around 1/2 acre. I probably won't have pigs after this year as the breeder I get them from is taking a break from farming, and I'm most likely going to focus on just goats and chickens for a while. But if I was going to keep the pigs long term, I would probably divide the pig field so that I could rotate their field.
