I'm new to ducks. I have 3 female lavender Muscovies who won't go into duck house ( within electric pen) They roost. In Very high 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. Guessing I can't so, 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 duck droppings on roof for long! It's funny now but won't be once a big mess appears! Also when they lay (still too young to) where will they do so if they aren't used to a house?!
