Well, I have turkey hunted for 15 years, 11 successful, thank god. Last year, one of my new hunting buddies was hunting on public property with the same problem. Two morning in row had Toms gobbling on roost then flew down past his blind and never seen or heard from them. So, he called and that afternoon went out and looked at his blind, brushed in nice, but I told him we need to move it, the sun was coming up and shining into it, any movement picked up. so we moved it and I had the next morning off and we hunted. He had nice spread of hens and jake, looked perfect after we moved it. That morning we was driving up, and talking. I asked if he seen any Hens fly down he said no. Then I asked if he heard any tree yelps and or tried fly down simulation and scratch leaves, he said no. I then asked how early he got there, he said just light enough to see, bingo! I told him that this can screw you when hunting close to birds on roost, they may see you approach and/or get in blind, heck walk right under hens and not even know it. So we got there with about 20 minutes before first light and set up in blind. Birds started gobbling, and flew down, into the little clearing, about 50 yards from blind then went off in woods. He was upset, I said why? didn't you hear those hens, he said no. So, we was ready to go, had to work afternoon. I stayed, and waited around for 3 hours, then did some calling and called in two toms to within 15 yards, didn't have permit so just watched them. Next, morning we got back there, and I told him I want to try something, if he was game. he got in blind I moved 30 yards into the woods, putting the blind between the toms and me and as soon as they gobbled, I tree yelped, did a fly down and scrathed. three toms flew down to with in 30 yards of the blind, (I told him not to call just shoot, before hand). I gave a few soft purrs and two gobblers strutted and came to the decoys. My buddy shot a 22# with 9" beard and 1" spurs. Afterward, we was talking another factor I didn't realize was how he had his decoys facing. Before we moved the blind they faced away from the blind, when I moved it had them face toward it. Beleive, that the birds seeing him come in. teh decoys, and believing that the hen was past the blind assisted in harvesting this bird.
