RE: Will birds return when....
After I shot my very first turkey years ago, I went over to grab him (four other gobblers were with him and all had flown off at my shot). About 2 or 3 minutes later, a gobbler sounded off about 60 yards away.
A friend of mine killed two one morning. He picked up number one and another one gobbled nearby. He went right back to the same set up and killed the 2nd one minutes later.
Your chances are very good.
