I got 3 baby ducks yesterday. We don't know if they are boys or girls (we will when they are older ) But when they are older we are going to build a pen for them. It said female ducks will lay eggs even if there isn't a male present. If they lay eggs, and we collect the eggs, are they going to turn into ducklings? How will we know if they have been fertilized by the male? If we collected them to late, and the male fertilized them, but we put them into the fridge, would they not turn into ducklings because they are cold?
