Below is a video I took one night during evening chores. I went into the duck pen to change our their always gross water. I asked Rialey to come in with me to help keep the birds out of my way. Tonight she decided to practice moving the flock while I dumped, rinsed, and refilled the buckets.
I will allow this kind of behavior as long as it is under my supervision, and the dog and stock remain calm. I think this kind of doodling with the stock is the way that herding dogs learn how the stock move in response to their pressure and movement. I watched Luna do it many times and every time she would seem to come away with some new knowledge about how to better handle the stock. I also think it is very interesting to watch Rialey create then solve problems, split them apart them put them back together again and move then into and then out of the enclosed area calmly.
**You may want to turn down your speakers for this video. Ducks and geese are loud beasties. Also, please excuse the mud. With rain almost every day, there's not a lot we can do about it until the weather dries a bit, and I assure you that the waterfowl in this pen do not mind a bit. (Plus they spend most of their time free ranging in the somewhat drier pastures.)
