Turkeys are just really making some good numbers in alot of states. Plus several states its illegal to take hens in the spring, but some allow it in the fall. I don' t think any are at a serious population boom that' d be detrimental to the flock. Although turkey' s can become nuisance to farmers crops, they hardly do the damage to the environment that can cause problems for the overall population like deer do. Turkey' s eat alot of bugs during the year, where deer strictly eat plants. Deer can decrease there food sources when overpopulated to the point that it does so much damage to the woods, it takes yrs for it to recover.
If I was you I' d keep watching those hens. If you know a toms in the area, he may not have his hareem of females gathered up yet. I' d watch the hens, as well as continue to try, and locate him!
