I think the muscovy is a female and the pekin a male. They are both about 11 1/2 weeks The pekin is a lot larger than the muscovy. I dont know how to sex by sound bc ive never had ducks before them and i cant compare sizes cause they're the only two that i have. I can see that the muscovy's carnucles are coming in cause its pink around where the beak meets the face. I'll post a picture of them when i get a chance
