My Indian runner duck has made a nest and has randomly sat in the nest for a while but there is now 20 eggs in there and she is still not sitting on it full time. She moves the eggs around and keeps laying in the nest. Before she created this nest she would lay all over. I do date the eggs daily to keep track but I am concerned that she is not fully in touch with her mothering instincts. Any thoughts, concerns, or helpful comments are welcome. We are new to all of this.
