Using the wind to find the game is exactly what you want. But when they locate a nest and the bird took off running, you also want them to be able to trail out birds. This will come when you use moving birds in training, nothing to worry about at that age.. But you can do as said above. A great point is to hup or place, (sit), your dog, let him see you drag a bumper scented out in some moderate cover down wind. Don't throw it, drag it. Of coarse he has to stay or be leashed back for that. Stop several times on your way and make eye contact. Go about 40 - 50 yards and leave the bumper. Stop a few times on the way back, this way he has to guess where you put it. Let him go with your command, find it or whatever, and see how he does. If he gets it, fine if he struggles walk closer till he gets it. Once he knows its there he will try harder each time. If he struggles you can also shorten it up. Most dogs will figure this out quick though and offer little help other then blind retrieve drills and taking a line. You ultimately will need the moving bird, clip wing pheasants etc. But get him through the flushing and finding, retrieving etc. first. the moving birds will come. When he is ready take a small hen and tape her wing so she can't fly, elec tape. Then wet her down with a mister bottle and some scent if you like as well. Toss her in the grass right in front of him and wait till she runs off a good ways. Let him go. He will get it after a few tries. Be happy he is using the wind..... It's a good thing, always.
