They are Potbelly pigs. But around here, you usually end up with the mini versions that do not get to typical PB size of 300#.
Have both mom n dad.
Piglets are born ready to go, they escape their sacks on their own, find a teat on their own, huddle together and even are potty trained from birth. They will wander away from the nest or to the edge of it to go pee and poo, then hurry back.
