I have two ducks 1 male 1 female. I recently found a nest that she made with 16 eggs that I could see in it. I don't know if they are fertile or not. I went to pick one up because I thought they are probably all frozen but it was warm so I put it back. Is she going to sit on them again? Also, she isn't always sitting on them, she comes out when she hears me for water and food and will stay out there for a little bit. Would I be able to candle them or is she going to abandon them?
