In my personal opinion, the answer would be NO!!!! Here's why. I recently built a new chicken coop, for 10 Buff Orpingtons. I completed the coop at some point in October, and knew I wasn't getting the chickens until at least February, so my wife and I decided to house our 4 Blue Swedish ducks in the coop until the weather broke. The ducks pretty much "free ranged" on our 1/4 acre pond all summer and absolutely refuse to go inside the floating ducxk house I constructed last year. That being said, my wife was concerned the ducks would freeze on the pond so we moved them to the new coop. IT WILL NEVER HAPPEN AGAIN.
The ducks were in the coop for about 3 months and in that time they ruined the floor with all of the water they billed out into the 12" of bedding. They have been out of the coop for 4 days and still the floor is saturated and I fear it will have to be replaced. In retrospect I should have put a vinyl floor down; however with the depth of the litter the lower portion of the walls are also saturated. Don't get me wrong I love my ducks, they add a bit of ambience to the pond, but chicken coops are for chickens. If I was ever to build another duck house it would have a wire floor.
Based on my experiences I would not house ducks and chickens together since ducks seem to enjoy spreading the water around and chickens enjoy things nice and dry.
Just my 2 cents......
