My Daughter and grandchildren want me to get ducks to go with the chickens and goats we have. I can easily dig out a small hole about 10 x 10 and keep it about 18 inches deep with water. But I'm concerned that the Ducks will prefer the big in ground swimming pool about 75 yards away. I've thought of throwing whole corn into their little pond to have them associate it with food. But will that be enough to keep them out of the pool? They want about 5-6 ducks, which would be enough to leave duck turds all over the cement sidewalk around the pool. Any advice?
