It's just an educated guess, part of my post-game and pre-game process every year. As soon as spring turkey season ends, scouting for fall begins. The cool thing about my opening day longbeard? One of the hens is sitting (the younger one). Biology tells us young hens don't always nest their first year, but this one is. On average, studies show jennies (as some call them) begin nesting later in the spring season than adult hens (if at all). If unsuccessful, they finish re-nesting attempts sooner.
