So well said Walt..
The old books are wonderful, gives insight into what the early foundation breeders were thinking, their early creations, what directions they were going..in my opinion a worthwhile read...but you wouldnt want to use some of the remedies of the day such as arsinic and other extreamly toxic treatments of the day..
I would like to add to that when clubs devide into warring factions, it is extreamly rough on new people trying to get involved in a breed..if they buy a bird unknowingly from a person then try to join a club for help and advise , suddenly thrown into a tornado of bickering and petty disputes it gets discouraging real quick..I have had 3 people get in and right back out due to the imaginary line drawn in the sand and people being assigned a side in these sad disputes...its not good for the breed..some of the breeds are already in a state of disrepair to the point where breeds are being added that shouldnt be ...but people get so lost in this bickering that they cant see what they are doing, and blinded to the point that if you try to tell them they cant hear you..Its OK and I stress OK to have a difference of opinion..it should never degrade into these sham wars..somone needs to be the grown up in the group and moderator..sadly that seldom happens.
What I would like to see is top breeders of today do updated poultry and breeding books with insight of today ..people turn to those old books because sometimes experts close down and wont help and the ones who do it gets lost in the blizzard of info on the internet.. especially APA and ABA..maybe they could corner a few top people to write ..when you go to book store or even tractor supply, there are pultry books avail..sadly they are not well written,you leave with more questions than answers...one of those books thou written just a few years ago also gives bad advise..it says to cut the feathers around the comb to give the neat appearance befor a show..I always thought you were to not cut a feather ..but because that book said so people swear by it....a few top breeders have written like Ray connor..experts and beginners alike can take away from his book..but you felt like you wanted even more...we have lost the art of poultry keeping and trying to re learn everything that was common knowlege at the turn of the century.
Unfortunately there are very few books about breeding that are fairly current. The best way to learn breeding is to find an old person raising your breed and pick their mind. Sometimes it is not easy to find one. It is not easy to get us old timers to write things down as we don't usually have the time to do it. Another way....and I think you are already doing this....is to talk to people at shows and learn what you can. Lots of the "advice" online is not very good or completely incorrect.
Two fairly recent works are Ralph Sturgeons Plymouth Rock book and the Sebright book by Bill Holland. Even if they are not about your breed, they have general advice on breeding. Anything by Fred Jeffrey is outstanding and should be read. It is about bantams, but that info can be used with large fowl. He was a poultry genius and passed about 15 years ago.
