I have what I think is a drake, and yes he hops on the one duck. But just the one his age. I've noticed the older ducks laying down for him but he won't get on them. I don't know why. I think there are 6 eggs in the nest now. When I go down, she is coming out of the house so I think she is sitting on them. Need my trail cam hooked up lolThat is just their nature. Nothing wrong with it at all. I let mine make nests because it’s a lot easier to find them than when they just plop them out wherever they are standing. If you want, leave one in a nest so they lay in the same spot everyday or pick them up daily. If you have a drake does he hop on top of the girls? He’s probably the boss too. You could always leave them in the nest and see if one will sit on them and hatch some out.
