I asked this same question a few months ago. I got an English setter at 12 weeks and started the training Day 1. He turned 7 months old this past weekend and is really coming along nicely. I used "Gun Dog" by Wolters and "Bird Dog" by Williams. While I have owned well over 100 dogs, this is my first bird dog. Those two books have helped me a lot. If you do a search you can find some more reccomendations. Like everything else, it can get to be information overload. I picked the 2 books that sounded most like "me" and went from there.
I am also going to buy a Soprtdog e-collar this week, and friends have told me they come with very good traning info.
