One of the highlights of our visit to John's was meeting the pigs... and the piglets. The pigs do an amazing job of clearing the land and are clearly very content with their lot. I'm including a quick video of John with Louise (I think!).
John has them on a steepish gorse covered slope, which they happily rooted about in, and it is stunning to see how effective they are at clearing the thicket of gorse etc, leaving John free to move them on and then seed the area they've cleared.
