I didnt think the pot bellied variety was all that edible,i thought they were more bred as pets and watch animals[like the geese you find in some of the Scottish distilleries,they make a hell of a racket when disturbed].
Strange markings on the spotted,ive never seen that type before.A farm i worked on the farmers wife kept two,they were similar to the left one.
They make excellent pets by all accounts and are quite intelligent[as are all piggys]
Its just unfortunate they taste fantastic when roasted all crispy like
