How soon do drakes start to show a curled tail?

[Birdlady65]

I have a duckling that is almost 3mths I think it is a female as the tail has not curled. I am curious to know how soon a drake would start to show this. Her mother is a black and white female not sure of breed & the father is a Khaki- Campbell.

Usually around 15 weeks give or take. However by now you should be able to voice sex accurately http://www.majesticwaterfowl.org/artquacks.htm

Thank You so much! She is definitely a female, which is great as it is what I wanted. I checked out the site you sent it was very informative for what I was looking for.
Your prompt response was great as I don't have a lot of time to spend on the net at a time. Thank you again.
