I'm new to ducks. I have 3 female lavender Muscovites who won't go into duck house. They roost. Trees or rooftops. Now they are roosting on my neighbours roof. I've tried training to food and they come in mornings but not in evenings. How do I train them not to roost , should I clip their wings but then if they still won't go into duck house foxy will eventually get to them. Any advice??? Neighbours won't tolerate a duck dropping roof for long!
