Khaki sounds like she swollowed a squeak toy

[Duckstable]

Hi all, one of my khaki girls has just (as in, in the last 30 min) started sounding like a squeak toy when she quacks.

She looks fine, is alert and isn't stressed. I put her in our quarantine crate I figured I'd see if anyone might have any ideas as to what's up.

Any way you can get a video so we can hear? Any signs of being broody? Asking because when they become broody they can make strange sounds.

Have you felt along her neck for any sign that she might have swallowed something and it's stuck? does she have grit available?
