There are some of the states that have grown their wild turkey population to outstanding numbers and we as hunters applaud the great efforts from all the states game and fish agencies. But the first theory is that there are too many hens in the woods so the boss gobbler does not have to gobble as much since the hens seem to be available everywhere.
Another popular hunter opinion is that we constantly take the vocal gobblers so by harvesting them. We are leaving the gobblers that are not as vocal and those birds are doing all of the breeding and producing offspring with the same genetics.
The final opinion among hunters is the how the hunting season falls in the state. Some years it falls later in the season and some year earlier, just depends on the calendar. Which if it falls later in the season the breeding season is over.
