Pigs are a naturally clean animal that will do their business in one corner of a bigger space. No smell. No stink. Brian says the only way pigs will stink is if you let them fester in one spot. The pig fence is stock panels held together with caribeaners. Brian is growing lots of stuff that the pigs will self harvest. The most important being sunchokes (jerusalem artichokes). But no matter where you move the pigs there is plenty more to eat, thus reducing the feed costs. Pigs love to eat blackberry roots - and are a great way to control blackberry problems.
