This was a predictable outcome of this study. Especially, since the folks doing the study said that it was a compromise(a shorter setback) to the dates that the season was pushed back. They stated that no one would tolerate the dates that it needed to be pushed back to based on nesting times.
We have already established that you and I don't agree on this, but I think you really misunderstood what was said about those dates. You first said something about this relating to the study in MS. Butler did say that they were not going to consider opening the season at peak nesting initiation, which would have pushed the season to 4/15 or 4/20. I don't remember the exact date they used, but they weren't going to consider a date that late, so there was no point in studying it. That seemed like common sense to me. You might as well make the wild turkey a fully protected creature, no different than a bald eagle, if you are going to start the season that late.
What they were willing to study was to see if there was any improvement in poult production by starting the season 4/1, or about 2 weeks later than the historical opening date. My understanding is that the studies in both MS and TN found no benefit. That should have been studied BEFORE changing the season dates, but it wasn't.
