Wisteria is usually considered moderately deer resistant, but that certainly does not mean deer proof. You know what they can do when they are hungry during drought periods. I'm not sure about turkeys.
Young plants will be most vulnerable. It would be prudent to protect then with a six foot high wire fencing. When they are up and over that height onto an overhead trellis they should be okay. Unless the turkeys decide to fly up and roost there and feed on the developing flower buds. I haven't seen any reports on that, but it may be a possibility.
