We saw an average to slightly above average hatch with what very few birds we have left in Limestone Co but that's only based on what I have seen and others are reporting to have seen over the summer and through sightings of poults during deer season. That statement is not backed by collected data or surveys by game and fish.
Killing an annual limit each year is not hard for a seasoned turkey nut if the birds are there. The hard part is being big enough and respectful enough to the sport to not kill every bird on your property and de bird an area that takes years to rebound. It take a whole bunch of man to listen to a lone bird left on a farm gobble his head off and the hunter just walk away and say your arse is mine next year.
Concerning the lone bird left on a farm at the end of April. Killing him the last day of season and killing him the first day of next season won't have any affect on increasing the overall turkey population. I agreed with most of what you said, but not that.
We still have birds breeding up here on the line on the last day of season some years. Some years all the hens are going to the nest at fly down by the April 20th.
