Voice change from peeping/cheeping to quacking

[mustangsaguaro]

I have 7 ducks in that this weekend they will be 4 weeks old. In the past couple of days I have noticed minute voice changes in some of them. Almost like a small quack coming out of them. At what age does the peeping/cheeping stop and you hear more quacking? I have also heard you can voice sex is this for all breeds or some? I have 2 call and 5 cayugas. The ones in which I'm hearing voice changes first is it possible those are the females or no way to tell at this point?

Thanks

This is for all breeds but Muscovy's much later on them. ducks will quack loud boys will be raspy, you might have something there though maybe girls just have to quack first. The quacking should begin to pick up and the girls will get louder and louder. still may take a few more weeks.
