Vocalization - Male vs. Female?

[Katybird80]

Are there distinctive different vocalizations between males and females? I have 1 male Rouen and 2 female Mallards.

Yes. Males should make a low, rasping sort of sound, and the females have a distinct quack.

Awesome! Thank you! I am new to Rouens and Mallards. I have only had Khaki Campbells in the past. I appreciate your help.
