Benny, we raised our ducks to respond to "All ducks go to bed", as we herded them in when they were little. When they grew up, they would line up at the coop at dusk to be let in. They laid eggs in the morning, then were let out for the day. It was easier to keep the bedding clean....well...cleaner. You are right about their being hardy. The first year, I worried about their feet...no need...
