Do ducks begin their proto quack at different stages

[austroberta]

Hello! I bought 3 Indian Runner ducks and requested females only. I hear one of them beginning her very audible proto quack, but the other 2 are still peeping. Do ducks start quacking at different ages? They will be one month old on Tuesday. I'm concerned I might be ending up with one female and 2 males.

Thanks!

They are still too young for voice sexing and are still developing adult voices - just at different maturity rates.

Thanks for your response! I thought that was the case, but I'm new to this, so I wasn't sure.

I recently hatched four Khaki Campbells -all turned out to be girls. One started her quack really early -like at two weeks old and the next joined her a few days later. When I gave them up at 3 1/2 weeks old a third had started. The person who took them said the forth started a few days later. So yes, they all start at their own pace. The good news is you know you have a least one girl.
