What age should you be able to sex ducks ?

Hi , I’ve got 6 Aylesbury ducks that are about 5 weeks old now and are near enough fully feathered. Should I be able to tell by now if they’re a drake or a female ? I know drakes have a curl at the end of their feathers but all the ducks look the same. Thanks I’ll add a picture below

Vent sexing on ducks is fairly accurate at 1 week old. But at 5 weeks is pretty hard. At this point I think you just had to wait for quacks and hissing.
