I did read all these posts and just want to add...If starting with hatchery birds, I would chose a breed you are interested in and get at least 25 of them. I don't think breed matters much unless pushed to the extreme. There are just as many differences with in a breed as there is between breeds. Let them free range as soon as they're out of the brooder. Keep them safe at night and let them fend for themselves all day. Hopefully you get a nice trio to breed with next year. These birds made it through the gauntlet and hopefully will go broody and teach the next generation. I do think a little American, or Oriental blood would be helpful for a sustainable flock. I'm wanting to use Sumatras, Australorps, and Shamo, keeping a pure line of each, but mixing yardbirds for personal use. Hopefully it doesn't happen but if worse gets worse, I can depend on my mutts to get me through.
