As the spring turkey season progresses into the later phase, decoy applications also change. I would classify the “late season” as the last 10 to 14 days of most spring turkey seasons. To ensure a greater chance for success you will want to mimic the subtle nuances of the late breeding phase.
Most hens are nesting or visiting nests at this time. Jakes are in bachelor groups and beginning their summer pattern. Gobblers are searching for the last remaining hens. This is the best time to incorporate a single hen with your decoy set-up.
