That's an interesting issue, culinarily speaking. At what point does the difference between free-range farmed and wild disappear? What if someone has an immense enclosed area with appropriate climate, vegetation, terrain, and diet. What's the difference vs. game? The gradations would make for a fascinating tasting.
As for chickens, they've been bred so far from their wild ancestors, they probably would have a hard time surviving any wild simulation, much less taste like game. (With a few possible exceptions, such as as Black Australorp we owned that was clearly wilier and tougher than the rest of our small flock. Interestingly, a friend who had been a poultry major told me that the Black Australorps were genetically closer to the jungle fowl original than many breeds.)
