I use the natural flocking behavior of our sheep to move them around the farm. With only 26 ewes I can move the flock into the barnyard, across the road to the Hill Field and between pastures without the assistance of a herding dog.
Once a sheep, usually one that is most curious and friendly, starts moving towards me in the field, the others follow. To complete the move I circle around the back of the flock, forcing the stragglers towards the rest of the group.
