I got 2 mated pairs of Indian Runners (Chocolate and Mallard) yesterday. We brought them home and immediately locked them into the "Quack Shack" for the remainder of the evening and night. This morning I was pleasantly surprised to find 2 eggs and 4 relatively calm (by duck standards) ducks. I let them out to free range because the weather was so nice and they seemed okay with the new surroundings. Well...now it is fully dark and even though my duck man said that they would put themselves back into the coop at night, they have not. They're right now in the middle of our pond snacking and dunking. I don't know what to do. I am worried that they will wander away. How do I get them to go back into the house? Suggestions
