I have 4 Mallards, 3 male and 1 female. They are all 9 months old. Delilah, my female has started laying eggs. Yesterday we counted 19 eggs, and I think there is another one there today. My question is when is she going to lay on them? I am concerened with how long they have been there without her on them. I know she lays on them at night but why not during the day? These are the first ducks we've had so I don't have a lot of experience. Any help you can give could be greatly appreciatedThis is her nest with 17 eggs and today with we think 20. .
