We have lost two drakes to coyotes or bobcats, so all the ducks are locked up now. I would love to allow them out occasionally, but none of them can fly and they tend to be a bit difficult to get back in their pen. How do others do this? We are close to some woods, and the ducks just go right through the fences in their explorations. The chickens all come back for dinner, but the ducks just tend to wander.
