Over the years, my husband and I have raised a lot of pigs. It started out when we were living in a travel trailer on the property I was given. We were looking for ways to eat well and have a little extra while putting everything we had towards building our own house.
There was a lot of land to clear and pigs are not the hardest animals in the world to grow. We had a good source of some of the best piglets around for a mere $50 so we built a fence and allowed them to free range.
If you have some extra space this is something worth considering for at least awhile. Pigs can cause a lot of damage and erosion if not rotated out of the pasture some. If you have access to buying a half or whole pig from a quality farm then you can do really well putting back some pork at a good price.
