Okay, so we already have plans to keep chickens (and possibly quail, not free ranging of course) and will be having a flock free ranging on our land. However we are also curious about keeping ducks. If we do decide to keep ducks it will be a lot later in the year, possibly even early 2017. There is a small lake/pond behind our house where geese like to swim around, we even saw a mother duck with all her little ducklings waddling around just outside it! So cute. So clearly it is suitable for ducks, it is a decent size too. This seems like the obvious place to keep ducks, but there is also another place. There is a small river running down from the fields/hills that runs under a bridge and into the sea. The part of the sea it runs into is a naturally occurring bay, there is a small island between it and the open water, with two small streams of water connecting the two on either side. It is usually very calm, infact I have swam there many times. Do you think if we built the duck house near the bridge, tucked in beside the small hill that they would walk down to the beach and swim in the bay? Or would they not like the salt water? The river is only very small, you could easily step over it. Thanks.
