First of all buy a standard of perfection. That will detail exactly what you should be looking for. As for shows, get a subscription to the Poultry Press. It lists all the upcoming ones as well as results. Lots of sites with pics but until you really get your feet wet showing, its hard to describe all the faults to look for. I've been very lucky to have 2 master breeders in the ASBC to guide me. The one is now in charge of the NSBA and wins at most national shows. I learn something new everytime I get to talk to them. It also helps to just talk to judges after the shows. Tell them you are learning and to walk you through why they placed a class as such. Possibly get ahold of your state rep and have them help. I've taken many people out to our farm and spent hours answering questions. Just getting good birds is only half of the battle, conditioning them for the show ring is the other challenge.
