I have a trough as well. We added a spicket to it so that I can drain it easily. I drain it with a cheap laundry hose. It drains down to about 2 in" or so, then I can dump the rest. It's easy enough. Its easier than draining a kiddy pool. I have a larger kiddie pool out in the yard, that I just step on the side until the water drains down far enough for me to pick up the pool and drain the rest. I'm sure bending the sides to drain will eventually wear on it, but it works as well. The larger kiddie pool allows the ducks to swim and dive under. But, it will kill grass, so I drain it every 3 days or so and then move it to a different place in the yard. The trough stays in the run so I'm not as worried. If I had it in the yard, it's easy enough to drain and move if needed. I also have the trough sitting up on two pieces of wood to get it up off the ground so that the spicket doesn't hit the ground.
