Seems to me the same sort of thing happened here is Wisconsin.

When the turkeys arrived, within a few years, the Ruffed Grouse were gone.

Folks say it is the habitat, and I'll give them that to a point, but in every county the turkeys flourished, the grouse took a hit.

I was in Northern Wisconsin around Park Falls this past September on a fishing trip and saw many turkeys along the shoulders of the roads. It will be interesting to see if they impact the grouse in the north woods.
