I'm just not a fan of pushing the season back, I've heard all my life that most hens are bred before the season opens. If true there's no biological reason for pushing it back. Now outlawing male turkey decoys and tents, there's a step in the right direction. There would be alot more gobblers left alive at the end of the season.
I'm not really sure where or who started this misconception. Biologically, season is SUPPOSED to start after hens have been bred to minimize impact on reproduction. TN was flying by the seat of their pants when they set season dates back in the 80s.
Remember, 2/3 of the entire seasons kill occurs in the first 10 days (and this was true even before fanning and reaping became so popular) When season opens has the greatest impact on population dynamics and availability (or lack of availability) for males to service the hens.
I can tell you for CERTAIN, based on 1000s of hours observing turkeys on my farms, finding nests, performing necropses on broken eggs to determine the embryological age of the undeveloped poilt within, and observing timing of poults that the vast majority of breeding starts April 7th through 14th, peaking around April 20th. Initiation of nests beginning April 14th, and peaking around April 28th. Sure, there are outliers... a tiny percentage of hens will mate in March and start nests end of March, many more however will mate and initiate nests in mid May.
BUT. I concede this is for a very specific localized area of southern middle TN approx 20 miles. Perhaps all the hens have been bred in other parts of the state by the end of March.... but I suspect not.
Before turkey hunting became popular, coincidentally, the very best hunting was mid April. By mid April, the subflocks had completely broken up and those satellite toms were desperate to find a hen. The very best hunting for long spurred birds was the end of April mid day... when their hens had left them and broken off to lay.
I MUCH prefer to hunt mid April, but with so many males being killed first 10 days of season, it became much harder to just find a gobbler to hunt. I've had to shift my trips up to opening week, because I would rather see, work, and hear birds gobble than kill one.
