My Rouen ducks are building a nest in the duck yard and have been laying for only a week. They were laying them in their duck house but now two ducks are laying in the nest in the yard. They covered the eggs up real good with moss. I was wondering if I leave the eggs alone and let them keep laying if they will sit and hatch them eventually? I really want to hatch some ducklings naturally. Or should I collect the eggs and keep them clean until they are ready to sit? Any suggestions would be great!
