A Muscovy duck eats about five to eight ounces of feed a day, and the wide range exists because this breed's sexes differ dramatically: a mature drake can weigh more than twice what a hen does, with a broad, heavy body to match. Hens in lay sit in the middle of the range, non-laying hens toward the bottom, and a big drake in cold weather may finish a little beyond it. Muscovies are also genuine grazers for ducks, harvesting grass, weed seeds, insects, and even small snails with enthusiasm, so the bought ration and the yard together make up the true total.
Sizing the Ration for Drakes and Hens
Feed a mixed Muscovy flock free choice rather than by a single measured scoop, and let body condition sort out the individuals: feel along the breastbone and over the back monthly, because a Muscovy's dense feathering and naturally hefty build hide both fat and thinness well. A drake who bullies hens away from the pan will look magnificent while the hens quietly go short, so use two feeding stations set well apart when a flock holds more than a handful of birds. Unlike production laying ducks, Muscovies lay seasonally and in clutches, so a hen's intake naturally rises as she comes into lay and falls back while she broods — she is an exceptionally devoted sitter and may eat only once a day at the height of it, which calls for feed and water placed near the nest.
How a Muscovy Actually Eats
Muscovies dabble and graze more than they shovel, but they still need water beside the feed — deep enough to rinse their bills and clear their nostrils as they eat. A heavy pan of waterfowl or all-flock feed offered morning and evening, with leftovers lifted at night, suits them well and keeps the pen cleaner than an always-full hopper, since wet Muscovy feed sours fast and this quiet, ground-loving breed will still eat feed it should not. On pasture, expect them to spend long stretches grazing like small geese, and credit that forage honestly: a flock on rich summer grass may leave a quarter of the pan, while the same flock on a bare winter yard finishes everything and asks for more. Offer grit free choice to birds eating whole grains or ranging widely, and add a calcium dish for hens in lay.
Young Birds and Seasonal Shifts
Ducklings grow quickly on a waterfowl starter fed generously, and young Muscovies stay on a grower ration longer than smaller duck breeds simply because they have more frame to build. Intake climbs in cold weather, when a large bird keeping warm outdoors burns real fuel, and eases during the moult, though protein should stay steady in the ration while new feathers come in. Older drakes that have slowed down gain fat readily on a finisher's leftovers, so move pensioners onto a plainer maintenance ration and judge them by hand, not by their impressive silhouette.
When Eating Patterns Signal Trouble
A Muscovy that stops grazing, sits with its head drawn in, or leaves feed untouched while flockmates eat should be caught and examined the same day, and limping in a heavy drake deserves prompt attention because foot problems worsen fast under that weight. A whole flock suddenly off its feed usually points to soured feed or fouled water, so replace both before worrying further. KinsLe's Care Teams keep Muscovy care consistent by assigning feed, grit, and water checks per pen and logging each one complete with a timestamp, so a brooding hen's special meals are never forgotten.
