I have been reading that girl ducks have a loud quack, and that drakes will have a raspy, quieter voice. However, I am wondering--if drakes are upset, do they have the ability to make a loud quack too, or are they unable to do it at all? the reason I am asking is that my rescue mallard, who I suspect is a girl, will make a very loud QUACK if she is upset, but most of the time she has a soft little voice and kind of sounds like a squeezy toy, chirping to herself. So I want to make sure I am correct about her actually being a her No drake feather either, but she is only 7 weeks old, and I don't know when those develop. Thanks!
That sounds correct for that age. They still peep, but the females will quack loudly when picked up. Boys do not quack loudly ever. I would say she's a girl
The older boys get the less ability they have to produce louder noises even when upset. You can tell a female because she will burst your eardrum if she's upset haha
