So I have researched it. I want to build a playhouse, basically, for 2-3 females and 1 drake, likely muscovie, in the spring. I know this is necessary: Ventilated Predator proof Swimming pool Straw or hay for bedding Fresh drinking water I know they don't need roosts like my chickens. I know I want it to be easy to clean. I'm wondering about draining the kiddie pool I have. Should I raise it off the ground a bit, add a drain hole and drain with PVC pipe attached underneath or how is that best done? Just pick it up and dump it out weekly? Is a dog house type thing better except one with a removable or hinged top? I lock my chickens in their coop at night and the ducks will be the same. Keeps them safer. My main predators are my own dogs. They are doing well with the chickens when they free range each day. They keep most other predators at bay, like raccoons and coyotes. I plan on 16x16 pen with either welded wire or possibly hardware cloth on the bottom. With the play house accessible from both inside and outside the pen. I want to put it near my chicken coop so I can use part of it for food storage for both ducks and chickens. It is planned as a playhouse because I have easy access to easy diy plans that I can do. Winging it does not work for me. I plan on using one side of the chicken run as one wall of the duck run. We live where summer is more of a concern than winter so it will be in the shade.
