Duck Feed Calculator — Duckling to Adult Layers & Meat Birds

Adult laying ducks (Khaki Campbell, Runner, Welsh Harlequin): 0.25–0.35 lb/day. Meat ducks (Pekin, Muscovy): 0.4–0.55 lb/day. Dual-purpose ducks (Rouen, Buff): 0.35–0.45 lb/day. Ducklings 0–2 weeks: 0.05–0.08 lb/day, scaling up to adult rate by 8–10 weeks. Ducks waste feed by dabbling — use dry feeders with water nearby but not directly accessible to food.

Short-term yes for adults, but it's not ideal — chick starter specifically lacks adequate niacin (vitamin B3) for growing ducklings. Ducks need 2–3× the niacin chickens do; deficient ducklings develop leg weakness, bowed legs, and permanent deformity (“spraddle leg”). Either use waterfowl-specific starter (Purina Flock Raiser, Mazuri Waterfowl) or supplement chick starter with brewer's yeast at 1–1.5 tsp per cup of feed.

At 18–20 weeks (about when first eggs expected). Layer feed contains 16–18 % protein + 3.5–4 % calcium for eggshell production. Switching too early (before 14 weeks) delivers excess calcium to growing ducks — causes kidney damage. Switching too late delays egg production and quality. Meat ducks skip layer feed entirely — finish on grower/finisher at 7–9 weeks for Pekin, 13–15 weeks for Muscovy.

Ducks need deep enough water to submerge their entire bill and head for proper cleaning of nostrils and eyes. Dedicated duck waterer or a deep ceramic bowl. Shallow chicken waterers alone cause chronic eye infections, nostril blockage, and stress. Provide a separate “dabble bowl” or small kiddie pool for full-body access — not strictly necessary but strongly beneficial for duck welfare.

Yes — ducks are excellent foragers that can cover 30–50 % of their nutrition from pasture and insects in good conditions. Free-range ducks need less supplementary feed (reduce kibble rate 25–40 %). Ducks are also natural slug/snail/pest eaters and benefit vegetable gardens once crops establish. Protection from predators (raccoons, foxes, hawks) is critical — secure nighttime shelter is non-negotiable.

Top duck egg breeds match or exceed chickens: Khaki Campbell 260–340 eggs/year; Welsh Harlequin 240–330; Runner 250–300. Pekin (dual purpose) 140–200. Muscovy (less prolific) 60–180. Duck eggs are 50–60 % larger than chicken eggs, higher in fat, and have stronger-flavored yolks. Baking enthusiasts prize duck eggs for richer flavor; egg allergies differ between chicken and duck, so some chicken-egg-allergic people tolerate duck eggs.
