Well, first, we got them because we live on a lake in a community. We thought they'd be spending a lot of time there. But they don't, at least not yet. They are outside during the day and they stay close to home in our very small back yard. We have some other ducks in the lake that don't belong to us. But mine keep to themselves. Right now they come in at night at stay in my garage in a pen we made up. But we're building a 3x6 house to be their permanent home. Only for nighttime protection.
I have a very different situation from most duck owners.

I know, it's nuts.
