When will a ducklings voice change?

[won023]

my ducks are 4 weeks ATM and I'm noticing a slight voice change already they go from peep to quack most of them have a loud kind of distinguished quack then goes back to peep? Does that sound male or female can they be voiced sexed yet?

Loud quack is female raspy is drake

Just like middle school girls seem to hit puberty before the boys, my girl ducks had voice changes way before the boys. As Miss Lydia said, those who have a loud quack are girls. To me it seemed like they couldn't control it and it would just sneak out. Sort of like when boys have their voices crack. My boys kept peeping for a long time before they got raspy. So, if it quacks=girl, if it is peeping=boy or later blooming girl.
