At what age does a male duck get the tail curl feathers?

[headred]

Can someone tell me at about what age the male duck will develop that tail curl? I really think I have female Khakis, but they are not quacking like my Pekin, who is a few weeks younger.

sometimes the drake feather doesn't show up right away. try listening to the voices. the males are raspy. females 'quack'.

i think that is correct. if i am mistaken, someone please correct.

My ducks got theirs at 6 months...I knew they were boys only because they are mallards and got their green heads...My mallards really sound alot alike I could never tell by how they sounded...My girls are really quite and the boys wont shut up..Its not quacking but they talk like crazy!!!!
