The odds are against getting a shot at that buck from the compromised stand. You're better off hunting him from somewhere else. During the rut you have more room to work with because buck ranges expand. Ideally, you'll set up in a place where there's a good supply of does for live bait. If you're hunting the buck on a feeding pattern early or late in the season, however, you've got a lot more work in front of you.
Bucks are extremely sensitive to hunting pressure when they're on a pattern.
When you spook a buck off a feeding pattern you may as well look for a whole new buck to hunt.
