how long do the breeding paris need to be separated from the flock?

[Gallusfarm]

My mixed flock has been free ranging together, and now I'd like to separate out a few pairs for breeding. How long should I wait before I can be sure that the father is who I want it to be?

Thanks.

I wait a month/4 weeks.
