For a long time I've wanted a pet duck, and I think it's finally time to bring one home. Problem is they aren't technically legal in my city. I'm considering the possibility of an indoor duck, though I do have a small pond in my yard. I think I want to get a Rouen duck. What I'm wondering is, does it matter whether I get a male or female duck? Is the temperment any different? I need a very well behaved duck to pull this off. Also, can I get just one duck or should it have a friend?
