I don't know about that... Three of my hives are located right at the edge of the woods where the turkeys come out and they have never bothered the hives or bees. In fact I have seen the turkeys intentionally avoid the bees, as in walk out of their way around the hives. So, I'm not too sure that this is your culprit. There are 4 common subspecies of wild turkey - of which we have the Eastern in the north east so I guess if you have different subspecies of Turkey that may explain the difference - also I know turkeys are opportunistic feeders so if they are extremely hungry I guess it's possible they are feasting on the bees... Although, my gut says - highly unlikely.
