Puck's pigs

Photo by Barry Wallace

What is it about certain free-range pigs that don't have to be fenced in?   I photographed the two above on the front lawn at Puck's Farm, on the 11th Concession of King Township on Friday afternoon.   They were rooting to their hearts' content.   They did not wander onto the road or away from the farm.   They seemed quite content to stay put on the verge.   Is it good training, or perhaps the breed?   I have noticed Vietnamese Pot-bellied Pigs, in particular, seem to have this agreeable and fortunate homing instinct.   The Puck pigs pictured above are, I believe, Pot-bellies and quite healthy and hardy looking; neither too slim nor too fat.   I spoke briefly to them and they were quite amiable.
Please comment if you wish.
