I slaughtered some 12 week old muscovy drakes today. The local variety were dressing out at 5 to 5 1/2 pounds, and the ones from JM hatchery were around 6 1/2 pounds. Nice breasts on the JM Hatchery muscovies, and the white plumage helps produce a good looking carcass. As a result, I will be culling my current domestic drake breeders and replacing them with JM Hatchery muscovy males. Just curious what other people are getting for dressed weights on their muscovy ducks.
