OOPS - they are out again - somehow the sheep have figured out how to get the gate open. It was a surprise to look out the dining room windo to see them wandering out side free. They did it not once but twice - finally Mom tied the gate as well as latched it. They knew they were caught being naughty because as soon as we went outside to chase them in - they ran straight back into the pen. Do you think they were playing a game?
