Looks like a girl quacks like a boy?

I hope the video can be seen and I am sorry it looks like it am torturing her but while duckie was chatting in the coop I scooped her up and when energetic she will bark back like this. It sounds so much like a boy but her colors are of a female I think? I hope i am right about it but the barking isnt quite like what I am used to with females? Could pastel calls have a juvenile stage where male and female fesrher in the same? Is she morphing into a male? She is biggest of group still between what I think is two females and definitely a small raspy white male. The other white I am sure is female she has been really talking since day one. This one, the pastel, the slight rasp has come into play during past 2 weeks , I could not detect it at all during first 5 weeks. They are 7 weeks old now. Any help is greatly appreciated.

All mallard derived ducks have males and females with the same juvenile plumage. I think this one is too young to do the voice test with. I believe it is 12+ weeks for that to be accurate.
