A trick I use is to take a pheasant wing and drag it on the floor inside and make a trail, then hide the wing some place easy and insight the first few times then hide it and make it harder once she has learned to play this game.

Make sure you get her attention point to the track get her to smell it, tell her she is a GOOD DOG! (Don't be afraid to get a little silly and happy with her in the begining) when she finds it and starts to hunt it up.
Once she understands the scent is on the ground and learns to use her nose on the ground it will become a fun game to play anytime.
Then when she is older take this game outside, eventually leading up to real birds.
Pay to Play hunts and bird clubs are really good in the begining, the birds are usually a little easier to hunt for novice dogs then wiley wild birds.
