I have 3 white Pekin ducks and how do you sex them and then I also have 8 khaki cambole that are 2 weeks the white Pekin ducks are about 1 month and 2 weeks
They are to old for vent sexing. You may have to wait a little longer to tell. At one month old, the females may be able to make little quacks and the males will lose their voice. When they start feathering out (at about 3 months old) the drakes will get a curly feather at the end of their tail. Good luck!
