Have You Ever Heard a Duck Make This Noise?

I've got a hen that does it all the time. She seems healthy, eats a little too well. Name's Squeaky. Lol

Have same question, my female pekin starting doing it a week ago. We were shocked, almost thought maybe she might be starting to quack? She never has before so idk. She is 7 months old, already started laying back in June 2017.
