There are many sportsmen who think that wild turkeys will eat VERY young quail, as in many parts of the US, as wild turkey populations climb, (in some places significantly), the quail populations seem to drop.
I've been an avid turkey hunter, call maker and conservationist for twenty plus years, and I know that studies have shown turkeys to be completely random, non-selective feeders. Perhaps if they came across some day old bobwhite chicks, they might pop one into their mouth, but I can't believe they could physically accomplish the act of eating a chick.
My guess, and I've seen it many times, your biggest problem will be the turkeys liking your place and becoming residents, roosting nearby the house and not venturing far away. They are a great gamebird, but having them roost nearby your bedroom window can get old pretty fast, unless you sleep through your roosters.
