I'm in Fond du Lac County......I've stomped Eldorado Marsh, Mullet Marsh, Sheboygan Marsh, Theresa Marsh and Horicon Marsh for ducks and pheasants over the last 20 years.
Ups and downs for both on each of those marshes over the years. There is alot of potential, but not much management in the right direction, in my opinion. Horicon Marsh has been a shell of itself recently for the waterfowl factory it has been, even for birds using the refuge portion of it.
The pheasants for those properties are mostly planted. Some do make it and have been successful at reproduction or relocation, but habitat is the issue for sustainability of any population in numbers. It's just not a priority on anyone's radar.
I harvest enough of each typically, but this year and last year were tough for both. The properties have and are changing, got to be adaptive to be successful, and the pressure from others has increased significantly too.
