Muscovy vs khaki campbell sizes

[FFFarm20]

I recently got my first set of ducklings amd after watching them grow within the last week, I'm curious as to how big each breed gets. The internet said domesticated muscovies get anywhere from 10-15lb drakes and 6-8lbs for females. While the khakis only gets around 4lbs. Is this true?

Muscovy drakes are big boys when mature. Those weights sound about right.
