I usually raise CRX from McMurray's in Salatin-style pens and have been very pleased with them. Low mortality, good foragers, nice big carcass in a short time, and good tasting. Last summer I bought a couple different breeds of layers for home production, and I bought some straight run because I think a good rooster is essential, even if you aren't hatching eggs. So I started butchering the excess roosters a couple weeks ago, and gotta say, they are a whole different kind of bird. First, it's the only time I've ever butchered birds in cold weather and the amount of down was staggering, compared to summer raised CRX's. Since I'm using them fresh, I do one at a time and dry pluck, so the down is usable, anyway. Second, the carcass is almost all dark meat, the broth it makes is almost beefy looking, and the taste is incredible. They are over 7 months old, and the meat is not chewy at all. We slow cook them, after hanging salted for two days. (Thanks for that tip, Adam!) They were in the chicken tractor with the CRX's early, and have free ranged ever since, they are Blue-Laced Red Wyandottes. The hens started laying at 6 months, dead of winter, minimal shelter, and whole grain supplemented diet. I will probably continue to raise the CRX to fill the freezer and sell, but I may get a batch of dual purpose roosters for the gourmet market (including us!)
