I had placed duck eggs under the broody hen and then at the same time exactly one week later I added chicken eggs to the clutch. Both the ducklings & the chicks hatched on the same day. The hen was kept in a small pen with all her hatchlings. The chicks would follow the hen and respond to her clucks, the ducklings would ignore her and go play in their pan of water. But they all would cuddle in together at night, even when the ducklings grew as big as their Mama bantam hen.
