New Roots Farm has a few 1/2 pigs available for sale:

At New Roots Farm, our Heritage Breed Pigs are raised on grass and pasture.  We use a rotational grazing system where the animals are moved into new paddocks with fresh grass and forage several times a week. Our pigs are very happy! You will be too after you try some of our succulent pastured pork.
