I'm new to the homesteading thing and I'm bad at math. How much land is realistically needed to have a homestead that supports a family of seven (five children)? What size should the garden be? How many hogs, cows, goats, etc.? My parents own forty acres in the Midwest, but my husband and I live in New England and land is much more expensive, so I'd like so suggestions on a minimum land quantity. We have young kids, so we also need to have room for them to run and play without worrying about trampling the garden or getting bit by the pig. Thank you.
