There are general overviews of the standard online, but for the complete breed standard, you must purchase the whole book from the American Poultry Association. http://www.amerpoultryassn.com/store.htm
Also, consider becoming a member. It's only $20 for a year, and it's a valuable asset for serious breeders.
Well I don't need to be a member I was just reading the American silkies breeder club thing it tells u the weight size length and everything about what they need to be to be breeder and show quality
Roada, I think you don't understand the difference between someone who breeds chickens and a chicken breeder.
Anybody can breed chickens. All you have to do is put roosters and hens in a pen, gather the eggs, put them in an incubator and hatch the chicks. You have successfully bred chickens.
