Recently we have a flock of sheep in our little village Almere Haven. The city counsel decided to have a flock to keep the grass short, instead of machines and mankind. It is much more green and funny for us to watch them so close by in a residential area. The sheep move from the one grassland to the other with a mobile fence to keep them together.
There are always some "black sheep" in a flock. In dutch this kind of sheep is called "Schoonebekers". They even have their own Facebook page "Schaapskudde Almere".
