Lot of great suggestions on breeding these birds.
I would add I think it's important to create 2 lines before one starts bro to sis matings to any great extent.
One line descending from each male. If it was me, I would: Just use the plan Judge Card describes in the chart here.

If one wanted they could pair each male up with each of all the females, creating 6 lines to use with Judge Card's chart.
If several of the "lines" were moved 500 miles apart, even better for genetic diversity.
In other news, found the local 4H poultry leader and he is very excited about helping me find dedicated 4H kids with
which to place breeding trios this year per Walt's wishes. I think it's a great idea too
