Some of the information that is published is accurate and a lot of it is not. My father told me 70 years ago to not believe everything I read and he was right on. I'm sorry but anyone who believes everything they read about poultry is naive. The older it is the more suspicious I am. Bad information was prevalent in the old days too and they also had their share of know it all that were prolific writers. I believe people like Eissens and Piet who can actually put good birds together. They may have a different Standard, but they could breed to any Standard because they actually know birds. It is one thing to be an Internet breeder and yet another to know how to actually breed good birds. I can't tell you how many know it all Crappy breeders I have seen in my 50 years of doing this. The know it all can never make good birds. FYI no one knows all there is about chickens, so never believe anyone who claims to be an expert.
