At nine weeks realy don't worry so much about following a trail. It is good that your dog was excited about a wing and attacked it. Try tying a wing to a dumy and playing fetch with it, or tying it to a string and making it dance around then sto and hold it still a lot of dogs will stop and point when the wing stops. Just work on getting your dog realy 'birdy' and excited at this point. A lot of dogs will point at this age but sometimes you have to put them in the right situation to get a point that lasts longer than a few seconds.
Definatly talk to your breeder and see if they are taking their dog out in the feild at all and see if you and your puppy can tag along. Most good breeders are great resourced becuse they want ot see thier puppies succeed.
BTW-What area are you in?
