The ewes have been moved to fresh pasture on our twenty acre block up the road. I have to walk them half a kilometre up the road and at first they follow me because they know that I am the source of all sheep snacks. However when they realise where they are heading, they take off and I can only keep up with the stragglers. Thankfully they know the way and always turn in at the open gate. You see, sheep really are clever or at least more clever than they are given credit for.
