I've heard that before. I've visited with game bird biologists here who say that any quail that are eaten are consumed by accident, that the turkeys don't look for quail chicks to eat. Skunks and raccoons are a lot harder on quail. Several years ago there was a guy who wrote in to the Kansas Wildlife and Parks magazine complaining that the introduced turkeys were displacing the native pheasants. Of course the contention is false, but beyond that, the pheasant was an introduced game bird and the turkeys were the natives.
