I'm new, so thanks for any help you can provide! I'm ready to get my first ducks in the spring and I've decided on 4 or 5 Khaki Campbells. I plan to install an in-ground pond... probably a hard plastic liner with enough room for their cute flipping behavior I'm planning to use a large pump to get the water from the duck pond to my 17'x15' garden (highly diverse heirloom crop population). I will pump the pond to empty and refill with fresh water 3x/wk in the winter and more during the summer. I will also install a "just in case" drain pipe that will empty outside the ducks' pen and down a slope. I found a reasonably priced pump strong enough to overpower the very slight incline between the pond and the garden and rated for 10mm solids. My question is, can anyone think of any drawbacks to this plan? Thanks!!!
