I started "hunting" upland game when I was about 10, going out with my Dad. I was the retriever.
He never used a dog. He seemed to know where he could find a Prairie Chicken flock or bush partridge (that's what we called Ruffed Grouse). Huns were hit and miss. That was well over 50 years ago when I started. I still hunt many of the same places. Dad wasn't up to too much walking, as he had chronic bronchitis and asthma.
As a kid with my trusty Model 39, I spent hours walking out on his grain farm, mostly following a large flock of chicken, maybe 150 birds. Once in a while, I would fluke and shoot one.
On a warm, calm day in the Fall, chicken won't fly very far. On a windy day, they will fly a long way. Often, when a flock gets up, there will be one or two left. That's when you can sometimes get a shot. Often, walking around a bush in a nice wheat stubble field will produce a flock. Chicken don't seem to wander very far, and over the years, I can go back to the same spots and often find birds.
Bush partridge are the same. I have hunted the same areas since the 1960's. I only take a very few birds in a year, if any. I love to get out and walk the fields on a crisp Fall day, or tramp my favorite bush. It doesn't matter if I actually shoot a bird.
Probably better for you to try to team up with a person who has some experience. You will find that you can develop a sense for the right kind of day, terrain, etc..
Good hunting, be safe, have good days hunting. Oh, and you won't need the latest whiz bang shotgun and bazooka ammo. I mostly use a Savage 24H-DL in .22/20ga that I bought new in 1967 or so. I can pop a chicken at a good distance with the .22, using solids.
