Do Not Brood Ducklings and Chicks Together

Solution

Raise ducklings and chicks in separate brooders.

Explanation

They have different heat requirements (ducklings often need less heat sooner), different nutritional needs (niacin!), and ducklings' affinity for water will quickly soak chick bedding, creating unhealthy conditions for the chicks.

Notes

While sometimes done, it's generally advised against for the well-being of both species.
