Keep in mind too that the bucks are moving more now, seeking doe groups and scent checking trail systems. Keep rattling that thicket and mix it up, morning, mid-day, and evening. Trolling bucks may be in there or nearby at any time. Does aren't in heat quite yet so the bucks are going to make the rounds to keep tabs on them. Doe bleats and estrous bleats into next week should produce some action, as will rattling. Watch the wind carefully and don't call unless you're in position and can shoot. Start soft with all calling and wait about 5 minutes. Your next sequence can be a bit louder and a tad longer, mabye 3-4 minutes. Wait another 15. Listen and watch carefully especially your flanks around to your downwind side. Also, play the wind & weather in terms of how loud you call. When it is dead quiet out (not today!) you can call softer. When it is windy, rainy, gusty, you'll need to get some volume out there. Loud thumping on the ground with a large stick will carry further and mimic hoof stomping. This can also draw a buck in quickly.
