What gender is my Khaki Campbell Duck 6 weeks old

[Little Cute Lily]

Hello! I was wondering if anyone could give insight if my duckling Alfalfa is a girl or boy. Here's pictures of plumage. I know male and female khaki campbell have different looks but is six weeks old too early to tell?

Definitely a drake (male duck) you can tell by the beak color as you can see in the picture below. You can also listen to the quack. Females tend to have a QUACK while males tend to still have kind of a peep and a raspy voice. You can sex them by the beak or quack starting at 5-6 weeks.
