Of course MMc says they won't breed true, and, honestly, IMO, I don't care if they don't breed true. I kept back one of my Pioneer pullets, and am very glad I did. She was the smallest one. But as a DP bird, she is top notch. Nice personality, she was the first of my spring hatchlings to lay. I'm expecting that by letting her play in my chicken gene pool, there will be some nice meaty birds come out of the mix. She's a dependable layer of nice big eggs. She loves the feed bowl, but pays her way with an egg every day. Rudy: did you keep a male and female Pioneer? Please post your results. Seeing that all of the Pioneer roos had barring in their feathers, I'm guessing that the female in the cross was a barred bird. I'm wondering if a nice meaty BO roo x PBR hen would give a reasonable reproduction of the Pioneer.
