Apparently Mr Amateur Farmer™ has had another stab at the shaving bit. I don't know if he was wearing a blindfold at the time, but a quick glance over the fence confirms this could well have been the modus operandi. We can now also see versions 2.0 and 3.0 running about.
On a non sheep note: I'm really glad he's got three daughters and not three sons. I dread to think what kind of brutal and horrible accidents might have taken place there if he had to explain and show them how to shave when hitting puberty.
