I have five Indian Runners and I'm looking to improve my duck pond situation. Currently, we've been limping along with a kiddie pool that I empty every other day. It's ok, but it wastes a lot of water and mucks up their yard. Recently I moved them to a night pen in the back of the garden, and dumping that much water there every other day is just not possible. What systems do you all use? Ideally I'd like to have a small duck pond that can drain with a soaker hose right to my garden. I don't know if anyone does this, or if it would even be possible with all the duck mess in the water. Thanks!
