You and I are likely to agree on 90% of turkey hunting subjects, including deks, fan crawlers, habitat, trapping, etc. But it's just not true to say that there was "no biological reason" for the change in season dates. There is no biological reason to prohibit the killing of albino deer. That was done through legislation because "they're so pretty." But regulating season dates to better align hunting pressure with the onset of nest initiation for a population of ground nesting birds with slow but steadily declining reproduction numbers is absolutely, 100%, by definition, a biological reason.  Recommended by multiple, thoroughly qualified biologist aside from Chamberlain. You may not agree with it and you may not think it helps, but that's a different conversation entirely.
