I am finding this fascinating but if you don’t want to, I understand. I have always had a mixed breed where the most important characteristic was being alive.
But, my DH created me a solid pen after years of makeshift and I am finally getting so chickens that stay around.
I have tried many of the aspects of this hobby, layers, meat birds, roosters, hatching chicks..,now, I am wondering if I would like a pure bred breed. And working on a SOP so I am glad to look at yours.
I am right there with you, as in know little, hoping more experienced will chime in.
