What breed and gender is my new baby duckling?

[chickensval]

So yesterday I got a new baby duck from a friend.She hatches them herself, Her ducks and chickens are free range and there are so many breeds.. I know that the dad is khaki cambell.. I'm not sure what breed the mom was but I think she was white and black spotted. The duckling is only about 3 days old. I'm hoping for a girl so I'm calling her willow for now.

She has a yellow belly, black back and head, yellow wing tips and yellow rings around her eyes. Her feet are black with yellow spots.
Thank you guys!

If her father was a Khaki Campbell, but her mother was a different breed, then she is a mixed breed. And it is too young to tell gender without vent sexing "her". It sounds like she's really sweet!

Okay so I found out that the mother was a black magpie. And how do you sex them? I wanted to try it because I would like to get a pair so they could possibly mate when they're older.
