I am not sure it is sensible to keep Pygmy goats with your pigs. The pigs will root, and make the ground muddy, and the goats don't like getting wet muddy feet. Also, can you split the stable? There may be ingredients in the goat food that the pigs shouldn't have. And in any case, the pigs may not let the goats near their own feed. We keep dairy goats, and I do some years keep weaners for meat, but the pigs are always kept separate from the goats.
Other people may know better than me, but it's just my thoughts.
