Pigs aren't supposed to jump
most lop eared's don't, but many prick eared's do!
Our mangalitza could clear a 3 foot fence if she wanted to.
Our tamworth when 8 months old used to climb onto a sow sleeping by a hurdle and get over that way.
Our middlewhite used to 'pitch-pole' over of her farrowing shed wall at feed time - she'd hurl herself at the wall and land with her stomach on the wall, she'd then lean forward and fall off forwards to us bringing the food! Luckily she only did that once she'd given birth!
