Our French White Muscovies are now 8 weeks old, and they are huge. They literally grew before our eyes, and the males now weigh in at about 8 lbs.
We were able to move them outside at around 6 weeks, and now they are fully feathered. Our plan is to begin processing the males at 10 weeks, keeping two of the largest drakes for our breeding program. The ducks are much smaller, and more nimble than the big boys.
We were surprised how aloof the ducks have remained. From day one they have always seemed to regard us with cool interest. The only exception to this rule is in the morning at first feed, when every muscovy is focused on dashing from the coop to the duck feeder.
Our muscovies have integrated well with our two remaining hens, and everyone lives as one blended family. Muscovies are easy to house, put themselves up at night, and don’t need large swimming areas to stay healthy and clean. The drawbacks we have found are the massive amounts of feed these ducks need to maintain the pound per week growth rate, and the very messy poo and water usage. We find they need a larger space than the same number of chickens because they soil everything around them.
