Is it possible to keep rouen ducks indoors? Or is that a little too far fetched of an idea? I would keep them in a mini barn/shed 46"x39"x34" at night, and in the day let them either free roam with diapers or keep them in a pen on a tile floor with shavings(tile cant be stained obviously). Oh and there would be 3 of them, 1 drake and 2 hens.
