I have been leaving duck eggs in their house for a few days now, and the girls keep laying in this same nest, all neat and tidy. well, tonite I figured i would take some of the newer eggs in to save up to put under my broody hen . The one drake came in as I was taking some eggs and he kept sticking his beak into the nest and tapping the eggs. Almost like he was doing an egg count and making sure they were still tidy. Is it common drake behaviour to want to keep tabs on eggs in a nest?
