You've gotten this pup at the perfect time! There should be no reason at all why you can't train him to hunt birds. I suggest you get a general purpose puppy book (try "leader of the pack") & get him socialized & also invest in some bird dog training books. I suggest the Delmar Smith bookby Bill Terrant (sp?) or the NAVHDA "Green book".You can train him yourself for probably the first several months, but you will eventually need help getting him introduced to game birds.
If you get into a training club such as NAVHDA or your local GSP club, you'll be able to hunt him next season.
Find all the bird dog forums you can & ask LOTS of questions!!
Congratulations on your new pup!!
