What kind of home have you guys built? Post your pics. I've seen tons of awesome ideas, especially on youtube. I have a greenhouse I want to convert, and put a timer to open and close the sliding glass door each day for them. Of course, I want it to be the coolest duck house around Here it is: The lake is right around the corner but its hard to see. I asked here a while back if they would be okay living outside. Ducks I've had in the past have transitioned fine. It was pointed out that a non-flight domestic breed is unlikely to survive, especially w/ predators. Some additional information that helped confirm duck survivalbility in our area, was my neighbor. Turns out before I moved here, there was one lone Mallard on the lake. Other birds, ducks and geese, did and still do come thru, but don't stay all year. The one lonely Mallard made them decide to get 12 baby Mallards. As they got older, they were introduced to the lake and the one lonely duck. They quickly became pack and lived many years. But eventually, its believed the problem was the racoons, over time taking them out. If Mallards couldn't survive completely on their own, my Rouens wont. But a place to sleep and be safe at night could make all the difference.
