Birds were far more quiet yesterday for us... Heard a couple gobbles, but no hens.
I picked locations of previously known high traffic and did some subtle calling. Subtle clucks and contented yelps and purrs on a scratch box... Had a pair come in quiet in the morning (which were not shot at)...
Same tactics later in a different location and we did get a gobble or two, but the birds came in quiet again.
Also while moving later in the morning, I will do some gobbling before getting to or setting up in my spot... I believe that hearing a different bird gobble, often helps to get things started.
