They really are! We've raised different breeds of pigs in the past and kunekunes are SO different. They have their moments, but for the most part they have such a sweet temperament.
So in the warmer months, we rotationally graze the pigs so their poop stays where it lands and feeds the soil in our pasture. As for during the winter, we keep the pigs stationary, and because of that, the poop builds up. (people who don't have land/the ability to rotate can keep their pigs stationary year round). Typically we do a deep bedding sort of system in the winter where every few days I'll cover the poop with alfalfa stems (we feed alfalfa hay in the winter and they don't eat the stems). We sometimes muck out the paddock once over the winter and pile the poop/alfalfa mixture into a big compost pile. When we do this, we usually leave the pile to age for a year or so, typically turning a few times over the year. We try to keep the piles accessible to our chickens, too. They love scratching through it and finding bugs. For us, we use this compost on our gardens. For someone who doesn't have a garden, they could put it anywhere to amend/improve the soil, even if not intentionally cultivating crops. They could put it on their lawn, around trees, anywhere on the land. Some people also sell their compost. Animal manure is so good at feeding and improving soil and most places around the world have heavily depleted soil.
