One of our hens went broody and was in the bushes with about 21 eggs in a nest. Had not so much as made a peep til today. My collie was very concerned and stood by the nest and the hysterical hen barking until I came and saw what was going on. I picked the hen up and set her down on the ground, and the collie herded her, extremely slowly and gently, all the way back to the hen house and in the door. 'You can shut the door now, Mom'. THEN said collie went NUTS - spinning, wagging his tail with his butt up in the air in a series of high speed play bows, spinning some more - grabbed a stick and ran around delightedly tossing it in the air. Herding is an incredible, incredible instinct.
