Arielle - thanks so much for the awesome posts - it's always fantastic to push ourselves to really think on what we're doing, where we are heading, and why. We should always question - ALWAYS!
I'll add something I haven't seen thus far in this vein of conversation, and something I feel helped me tremendously in the beginning and continues to help. I went to several open shows, and hung out in the sections where the birds I was interested in breeding were being shown. If you hang out & just be a "sponge" - look & walk quietly among the cages and listen to the conversation - you'll quickly find those who are serious about what they're doing. Ask questions and get to know the folks who place. When/if you decide to show yourself, introduce yourself to the judge after the show and get their feedback. Most judges are more than willing to give good feedback and, after all, they are the "final say" for conformation of the birds. Take your time, learn the SOP, get some good mentors, and find a judge willing to help. I've got a few judges that have helped me in the past and continue to help me by evaluating my stock and providing good (sometimes harsh, sometimes exciting!) feedback. You have to be willing to do as they say, though. A judge won't waste their time with someone who is not serious about breeding.
I agree with most on here that having a "master breeder" certification, while honorable and helpful, does not necessarily mean those folks are the only ones to go to for good, correct information. Join breed clubs, get the very best that you can get to start with, and the longer you're in this, the more folks you'll meet, and the more you'll learn. With your most excellent background, it will not take you long at all to have a VERY nice flock!
