I thought my pekin was a male for a long time because she just whistled, but then one day at around 3.5 months she quacked! And now I am finding random eggs around their yard :) She is about 4 months old I think.
So will non-mallard colored call drakes have a tail curl? How will I know if I have ducks or drakes? I hatched out two from shipped eggs this fall and they are black and white (maybe pied??). They hatched on my birthday (late October - what a great gift!) so they are almost 2 months old.
