Actually I won't even breed father x daughter or mother x son. My line has been preserved for just over 100 years now. I only get as close as aunts and uncles and maintain 4 breeding families. In addition to those four I refresh a line from the original breeder ever few years. He maintains dozens of lines and he and carefully track which of his pens my lines come from.
It requires very detailed records. I wanted to breed a father daughter at one time and he asked his advice and he discouraged it. By maintaining four pens I have quite a few years of cross breeding options available but I do have to retain a minimum of 8 cocks at any given time.
This is the reason I have only 2 breeds. And in about 2 years i have plans to reduce my breeding lines to only two in conjunction with another breeder who is doing the same thing. So I will run two lines and he will run two in my other breed. But i will continue to run four in the RC RIR because their are too few around.
