I have 3 ducks, 1 khaki campbell, 2 fawn and white runners, one male one female. They live with 6 hens. I started getting an egg a day Saturday and am pretty sure its from the Khaki campbell as she is older than the runners. The egg is in random places of the duck house, hen house and out in the run. Last night I put a box with some hay in the duck house so she would have a designated nest, but this morning the egg was out in the middle of the run laying in the mud. I have one hen who has started laying in the nest boxes in the hen house. Is there a way to get ducks to lay in a designated area? Thanks.
