As I was taking pictures (from our bedroom window) of the stately pheasant, I spied a black and white collie running along outside the perimeter fence surrounding the field. J and I both ran downstairs and outside to investigate. All the sheep and lambs had gathered in the quarter of the field nearest to the house and farthest from the dog. J set off to catch or chase away the critter. Lo and behold there were two collies trying to get through the fence. When they saw J they ran off in different directions. Now we need to find out to whom they belong. We cannot have dogs worrying, or even killing, the sheep and lambs.
