What is this sound my Rouen is making?!

It’s just started that today! Lol it’s like a whistling sound.
(9wks old tomorrow.) Unsure if it’s male or female. But it’s the bigger of the two Rouens doing it.

One of my pekin ducks that is around the same age started making a similar sound about a week ago. It is going away and has not caused any problems, but I am still unsure what is. So, I wouldn't worry about it, but make sure to do your research (if you can even find anything, I couldn't).

I was thinking it was puberty! Lol but idk. First time duck owner.
