Alot of "serious" breeders (the ones with the best birds) are just in it cause they love the birds or the breed. Start a conversation with a breeder and if they seem eager to tell you lots of stuff about the breed of bird, showing, chickens in general and that sort of thing then they may be a good breeder. If your just getting into the hobby breeders will often give you good birds for low prices because they want to see you get into the hobby. If your a teenager even better because they want to see the younger generation get into it. I'm not saying that the talkativeness of a breeder will determine the quality of there birds, but someone who really cares about the hobby isn't going to bring or sell sick birds, and will probably be honest in a sale.
