we had angora/mohair goats when I was growing up. The billies can be a bit of a pain during rutting season. They are nearly impossible to keep from the females and climb, force though and otherwise figure out how to get around fences and other barriers. And they often butt you. But, great animals overall.
Cool! This was our first time seeing them up close.
They are great for clearing thistles and brambles from paddocks, and for keeping the grass down in rocky areas where mowing is impractical.
