If you are in WI how far from Mt Horeb or Cross Plains? I don't think I have heard of any discoloring but emaciation, yes. CWD attacks the brain so if it were walking strangely I would say odds are close. It could also just be an injury but if a deer hit its head so hard to skin its skull (hit by car?) I would think that would have killed it. If not could be infection now. Where is your town in relation to the elimination zone?
