I would not intro an adult pointer to birds that aren’t strong fliers that will lead to her believing she can catch or crowd birds
Wild birds would be the best to expose her to , find a low grass field pheasants are roosting in and get there at sun up let her find birds that will flush
Talk her up when they do, she will probably chase at first, let her, she will figure out she can’t catch them
after she exhibits she’s interested shut up and let her figure out she can’t catch them and she will begin to point, a point is simply her stalking and she will point eventually
Keep at it and encourage her if she’s got the instinct it will happen
If no wild birds
Bring her to a shooting preserve with good flying birds on a weekday when no one else is there so no shooting around her Until she’s demonstrating a strong prey drive and follow the same steps as I described on the wild birds above
It’s important to Get her real birdy first then introduce the gun afterwards don’t rush it
And we don’t train dogs to hunt they are born with that , we train them to cooperate with us
Good luck it shouldn’t be hard at all if you have birds to expose her to
