During turkey season , the birds transition through several stages. The more experienced you become , the more you will begin to recognize the different phases they are in. It will take me too long to start going through each one and the birds behavior in each of them. To answer your question , gobblers normally become more receptive to calling as the season progresses. What happens is a hen , once bred , builds her nest and begins laying. She will normally lay one egg a day until her clutch is complete. Once that happens she starts sitting all day. The gobbler gobbles to attract hens. The hens will show up daily and at first the hens stay with a gobbler all day. When she starts laying , she sneaks away earlier and earlier each day. Then one day she doesnt show up even though he has gobbled continuously. At some point during season the gobbler will be alone. At this time he is the most vulnerable. So keep after him and at some point he will be killable. Wether or not you can pull it off comes down to how you hunt him. Good luck.
