I could be wrong but I remember when I lived in Wisconsin and we had a Noon cutoff. The main reason the biologists there were wanting the Noon cutoff was an issue of hens not getting back to their nest before dark when they were flushed by hunters. They abandoned their search and roost and the eggs get too cold over night and do not hatch.

Of course a later study revealed that the percentages of this happening were very small and WI extended their time out. Like usual, this happened after I left the state!!!

Your state might site the above plus the fact that it reduces the hunting pressure for 4-5 hours in the afternoon.
