Without naming names...here are some of the responces that I have recieved from acedemia concerning my query.
"....Thanks for your interest in this interesting array of chickens. Most are not in commercial production so published data is rare. I am forwarding your request to the American Livestock Breeds Conservancy where the staff may be able to better direct you to published sources.
"I don't know of any such data, especially published, peer reviewed. If its out there, it's not reliable - more something like you'd find in Mother Earth News or such. A lot of people misunderstand and think poultry scientists work on such issues. But there is no funding for this type of work. All new data is for commercial poultry. You might find something in very old literature, like the 1920s or 1930s. The birds you see today were bred by the show people, and most are just a shell of what they used to be. No one has kept up on breeding for soundness, no matter what they tell you. Sorry I can't help."
"I have read a few of the really old extension pubs from university before the start of ww2 and found them to be surprisingly good. Those old breeds have never been improved since that time so the data is still pretty good. Good luck on your project."
"Google search the North Carolina Layer Performance and Management Test. Look for the 38th test report Vol. 38,No. 4 and No. 5
There is other works but they are very old for the other strains typically from the 1930- 1950 range." This was a very promising lead and has absorbed a bit of my time this last weekend.
Thank you all very much for your posts to this thread; and should anyone come across any PUBLISHED Research on these breeds, or any of the Heritage Breeds, please post to this thread so that we all may benifit from it.
My search continues.
