When I bought my poodle we weren't sure if she would hunt or not. Here's what I did.
I picked one toy and used pheasant or quail scent on it.
I kept that toy in the closet, and when it came out we played very hard with it, tug of war, fetch, and just made sure that the toy meant FUN to the dog.
That toy was not left out. It stayed in the closet and only came out during a designated "play/train" time.
Once my dog got excited at the sight of the toy, I would lock my dog in a separate room and drag the toy through the living room and hide it behind the couch or somewhere that wasn't obvious, but wasn't too hard to find either. The dog then got used to following the scent to the toy.
Then we did the same thing in the backyard.
Then rubber banded a pheasant wing to the toy.
Then moved to dead birds.
Then to live quail or phez.
Not sure if what I did was correct or not, but it worked for my pup. Pretty quickly at the sight of a wing, or the smell of a bird, she got all excited. After one or two live bird training, she quickly understood the game. Then it was just a matter of teaching her what her range was, and then moving to steady to wing and shot.
I am by no means a pro, but my dog finds birds and brings them back while staying in range (most of the time). She certainly wouldn't win any trials, but she is the best hunting companion I could every ask for.
Keep training sessions short and fun with a lot of positive reinforcement. Worked for me
