So some of you know I am new to this and posted a few times about my Rouen duck starting a nest. She has 11 eggs in it, been burying and unburying them daily when he lays a new one. Today should have been the 12th egg but instead she buried the other 11 and broke her 12th one leaving it far from the nest. Any thoughts on why she would do this to this egg? Maybe she has the eggs she wants and doesn't want any more?
