Where do ducks sleep in a chicken coop?

Ducks sleep on the floor of a chicken coop, not on roosts, so housing them with chickens requires floor-level bedding space deep enough to keep ducks warm and dry through the night.

Unlike chickens, ducks lack the instinct or foot structure to grip a roost bar — they settle directly onto the coop floor in a loose group. In a shared coop, this means ducks and chickens naturally separate by vertical level: chickens claim the roost bars overhead while ducks cluster on the floor below. The critical variable is floor space and bedding depth, since ducks produce significantly more moisture than chickens and wet bedding leads to respiratory problems for both species.

• Ducks sleep on the floor — they do not and cannot use standard chicken roost bars.
• Recommended floor space for ducks in a shared coop: at least 4 square feet per duck.
• Duck bedding should be replaced more frequently than chicken bedding — ducks produce roughly 3–4 times more moisture output per bird.
• Minimum bedding depth for ducks on a coop floor: 3–4 inches of straw or wood shavings to absorb moisture overnight.
• Coop ventilation requirement increases when ducks are present — ammonia buildup from wet bedding is the primary health risk in mixed flocks.
