He or she? Unsure what sex is my duck

[Pompona]

Hi everyone, I have 4 khaki campbell ducks. One for sure is a drake (raspy voice, green feathers), and two of them are females based on their "honking" voices and feathers. But the last one was until recently a female, or so I thought. " She" is noisier than than the drake and her voice doesn't sound raspy, although not as loud as the other females. But she has developed curly feathers, so I think "she" might be a "he". It is the white duck in the video. What do you think? Thanks!

Wow, very interesting! This actually happened after I rehomed two drakes that were part of the ducky family.
