length of time away from cock bird to ensure paternity?

Hi,

how much time does a hen need to be away from a cock bird that has mated with her to ensure paternity?
I have a hen that has been mated by her brother and has laid eggs - in spite of not having a nest box. In view of her determination to breed I am going to pair her with another unrelated cock bird who has also mated with her and I want to ensure that the chicks will not be from her brother!
Many thanks

I have read that it takes 10 to 15 days, "or more," from mating to egg laying. Personally, I would think to be absolutely safe, I'd say 15 to 20 days. Good luck! Jeanie
