We eat almost all of our cull cockerels.
I have never weighed them after butchering. They do taste good.
We sometimes try to hold "Heritage Breeds" to a level that they never were. What we deem a good carcass was probably not what our ancestors deemed acceptable. I remember some pretty good chicken dinners at Grandmas back in the day, and some of those birds were not all that meaty.
As for Frank Reese's birds, he has been breeding for meat for along time. This has the same effect as breeding for eggs. So are his birds truly DP?
The GSBR are by far the meatiest non CornishX birds we have had, but they won't set the world on fire as layers.
Our Columbain Rocks are also really meaty and very good layers. They still need a little work to get SOP, but are a fine bird.

thanks for your response Ron! I know Bob has quoted 180 eggs a year for the HRIR. I could live with that if I had a better carcass, than what I have now. Is your lay rate on the GSBR less than 180? I need to read some books on breeding, because I don't want to order from a breeder and then not be able to maintain the quality that I desire. On post #43 of the Heritage Large Fowl thread the Hogan method is described which envloves weighing and a physical examination for "fleshing" Can the physical exam be self taught or would I need some help with this? I'm not real keen on handingly my birds and they don't like it much either, but it would seem important if one is selecting for meat production.
Thanks again,
Mark
