I donít have any idea how far that is from a stocked area. But pheasants, especially the roosters, will sometimes show up a long ways from where they had been stocked. During the most recent banded pheasant study, two years ago I believe, they had roosters that were killed on the highway ten miles from where they had been stocked. Who knows how far they might have gone if they hadnít got hit on the road.
But, there are also a number of pheasants that get released by someone for hunting or just working their dog too, so who knows where they might have come from.
