We are currently looking into heritage breeds and want to get a dual-purpose breed good for both eggs and meat production. We are planning on doing a meat production a la Joel Salatin with the chicken tractors, and to have little pastures to rotate our egg chickens on. We want a breed that we can reliably raise year to year and hopefully not have to buy chicks again and again(though I think it's fun to get different breeds!). We are considering Delawares. I realize that the Delawares are a cross between Barred Plymouth Rock Roos and New Hampshire Hens... If you breed a Delaware hen with a Delaware roo, do you get consistent Delaware chicks? Do they breed true?
