Sexing Rouens by color

[Dancinbaer]

I read through several threads on sexing and understand sound, quack or hiss, is the best way other than looking for the corkscrew method. But seems I read somewhere that one has a single black stripe across the eyes and the other has a double stripe across the eyes. When our two were still weeks old I remember the bills and feet were different, one more black than the other. Can anyone refresh my memory? Thanks!

Rouens can't be sexed by color until they have their adult feathers.
So if they aren't sexed in the first couple days after hatching, it is wait and listen.

But keep your eye out for the drake lets green bills.

I have khaki campbells 3females and 2 males my one male has a green head and a green bill my other has not nearly as much coloring and his bill is slatish coloring. The only way I have determined for sure they are the obvious males is the curled feather.
