Figures for 4 adult ducks
| Figure | Per duck | 4 ducks | Source |
|---|---|---|---|
| House floor, minimum | 3 sq ft | 12 sq ft | Penn State Extension; University of Maryland Extension |
| House floor, indoor figure | 5 sq ft | 20 sq ft | Poultry Extension (extension.org) |
| Outside run | 15 sq ft | 60 sq ft | Penn State Extension; University of Maryland Extension |
The 4-duck column is the per-duck figure times 4. extension.org does not publish an outdoor number.
Why 4 x 5 ft
4 ft × 5 ft = 20 sq ft. That equals the 20 sq ft extension.org figure for 4 ducks, so it also clears the 12 sq ft minimum. A 3 × 4 ft house is 12 sq ft: it meets the minimum but not the 5 sq ft figure. Enter your own size in the checker above.
Other flock sizes: the duck coop size calculator and the 6-duck house. The per-duck figures are explained on how much space ducks need and listed in the poultry space requirements data. Keeping chickens too? See coop size by flock.
