I'm in NW Illinois and my county has CWD in the wild. I would just be getting started in the deer industry but I'm trying to determine if it's worth the investment in fencing, or will cwd have a heavy impact on business. I do know that there are many farms north of us that still operate in CWD infected areas. I dont know if that affects their outside of state sales, even if their herd is CWD free. I'm sure you would have to frequently test for it.
