So.. one of my Cayuga ducks went broody about a week ago. I was unsure if I should seperate her from the rest but one of my allotment pals said to just leave her were she was.. then a few days later another started to sit with her and refused to move and now a few days later again a 3rd has joined them. I managed to count about 20 eggs under them. Would it be best to try and seperate them all and decide the eggs between them or just leave them all to sit on one big nest. They all seem happy sat together but I don't want any fighting over ducklings once they hatch.
