UPDATE:
I went back on Saturday. I change my strategy by adding a second (feeding) hen. I did not bring any Tom or Jake in the early morning this time. Hens weren't calling at all, all morning. Gobblers were gobbling at the crows really early.
However, 7 hens came to my decoys and hanged around for a bit feeding in the area. I was pretty excited cause I've never been able to get the hens to come, and I thought the toms were going to come hang out. To my surprise, nothing... hens never called, eventually they moved, they were wondering around the field all morning without gobblers. what the hell is going on!?
