Most breeders keep the roo and hens they want to cross confined 24/7 to a pen by themselves to ensure that only that one roo fertilizes the hens.
It takes 2-3 weeks for the sperm to clear the hens reproductive tract.
So if you want pure Bielefelder's, Crested Cream Legbars or Lavender Orps....you have to keep them totally separate for about 2-3 weeks to ensure any eggs are fertilized by the correct rooster...by either keeping them confined to pens or rotating who you let free range each day, only letting one breed at a time range together.
what aart said,,, roosters don't breed at night in the dark,,, they do it during the day when out and about
i would like to point out that if one of your ducks is a drake,, he too, may just try to breed your chickens,, if he does, he will have to be penned seperatly,, duck anatomy is much different than chickens and can hurt the chickens
