Khaki campbell ducks.

[1st time]

I have been told i may have khaki campbell ducks. They are about 2 and 1/2 months old. I have a total of 6. Tow of the have light colored bills. One of the 2 light color bills I 5hi k there is a fether turning up on his tail. I have been told and read that male ducks do have feathers that curl in their tail. But does the male also have a different color bill than females?

Some breeds of mallard derived ducks, the hens will have an orangey/brown bill while the drakes will have a paler almost greenish tinged bill. Drake curl in the tail is a sure sign of masculine gender as is a raspy voice rather than a loud quack.
