I would stick it out right where you are at. I had 2 toms come up to my decoys yesterday and they both were together with 2 hens. I saw them there this morning as I was getting there ( left late this morning ) but spooked them. I gave them a couple of ours and went back and tried them again. I only had them gobble a few times as they went deeper into the woods. I will try it again in the morning to see what happens. I couldn't a shot at them yesterday because someone was trying to call them directly across from me so I let them go.
