Raising ducklings differs from chicks. They require a lot of vigilance but they make gentle and lively pets.
You can use a heating lamp or red heat bulb in their brooder space. Start with the temperature around 90°F and lower the temperature daily.
You can use straw or hay. These are friendly materials for duck nests and insulate well.
Though baby ducklings do not require water to swim in, they do need some water to dip their heads in and clear out their nostrils.
Feed your ducklings chick starter containing around 20% protein for the first two weeks.
