To be perfectly Clear, I don't have any chicken breeding experience yet, But I have researched for a couple of years now to learn what I can.
I have learned that the two "code words" for chicken breeding are "selection" and "elimination". Select for the qualities I want, and eliminate the ones I don't want.
I have learned that there are two differn't kinds of matings. "compenstation Type"- Where one bird excells where the other falls short Which improves points, and "complimentary Matings" Which is the mating of birds that are very strong in the same points, to lock those points more into the strain.
I have obsessed for 2 years over picking the perfect " plan" but from what I now understand from talking to people, and reading books any plan is destined to fail if we don't observe the things that I listed above.

Saladine Recommended to me a "rolling mating" which is a two pen system that uses very litttle record keeping and few males.
basicly it works like this.
Year 1 start with the best females you have and a male.
year 2 work with two pens. put last years hens and a young male in one pen, and the pullets you hatched in the other with thier father.
from there on it just keeps rolling. Alway culling down the old hens and retiring pullets to make one pen and the pullets hatched that year ( form both pens) in the pullet pen. Use the best old male you have on the pullet pen and the best young male you have on the old hen pen. Keep spare males. Craig russell recomends keeping 10 females and 2 males in each pen.
So that is what I think, Saladine might have to "mark" my little essay here to make sure that I am correct, but that is the way I understand from my research.
Hope this is helpful
