4 Pekins need 16 sq ft minimum (4 sq ft each). A 6×3 ft pond at 18" deep holds 6×3×1.5×7.48 = 202 gal. Changed 3x/week = ~2,622 gal/month.

2 Call ducks need just 4 sq ft (2 sq ft each). A 2×2 ft pool at 12" deep holds 2×2×1×7.48 = 30 gal. A small kiddie pool works perfectly.
Allow at least 4 square feet of water surface area per medium-sized duck (like Pekin). A flock of 4 Pekins needs a minimum of 16 sq ft of water. For full swimming, the pond should be at least 18 inches deep. Larger breeds like Muscovy need 6 sq ft per duck.
| Flock Size | Small Breeds | Medium Breeds | Large Breeds |
|---|---|---|---|
| 2 ducks | 4 sq ft | 8 sq ft | 12 sq ft |
| 4 ducks | 8 sq ft | 16 sq ft | 24 sq ft |
| 6 ducks | 12 sq ft | 24 sq ft | 36 sq ft |
| 10 ducks | 20 sq ft | 40 sq ft | 60 sq ft |
Without a filter or pump, change duck pond water every 2-3 days. Ducks are messy — they defecate in water, wash muddy bills, and bring in debris. With a biofilter and pump, you can reduce full changes to weekly, doing 25% water changes daily instead.
Yes, kiddie pools are a popular and affordable option for small flocks (2-4 ducks). A standard hard-shell kiddie pool (4-5 ft diameter, 12 inches deep) holds about 100 gallons and works well for dabbling. Dump and refill every 1-2 days.
A flock of 4 medium ducks with a 120-gallon pond changed 3 times per week uses about 1,560 gallons per month. Water usage adds $5-15/month to your water bill depending on local rates. Consider a rainwater collection system to reduce costs.
Calculate liner size as: (pond length + 2×depth + 2 ft overlap) by (pond width + 2×depth + 2 ft overlap). For a 6×4 ft pond that is 18 inches deep, you need a liner about 11×9 ft. Use EPDM rubber liner (45 mil) for durability.
