Blue Swedish duckling gender??

[Welsh Ducky]

I’m trying to figure out the gender of my four week old Blue Swedish duckling, Poppy, by voice sexing.
Poppy used to just peep, but now her voice sounds like she’s in the verge of a quack/honk noise, so I’d think girl, but it also has partial whistle to it, like it’s a boy...any idea how to attach a video so I can show you all what Poppy sounds like, and you can give me your best guess?

Do you have a Youtube account? Post the video there, then link it. This also works with some other sites, but I'm not a tech person, so I can't name any besides Youtube.
