I have 2 ducks currently. A khaki Campbell hen and a pekin drake. For about 1 week the hen was sitting on 10 eggs. suddenly she almost completely stopped sitting on them. It has been a week now and she still has broody behavior ( hissing, charging at me, covering eggs, acting fidgety) but I candled the eggs today and all seem to be dead. Idk what's up with her but I'm disappointed and upset now does anyone know why she stopped sitting on them, why she's still acting broody, and if I still have a change of her laying new eggs any sitting? Thank you
