Oh, Deer! News | March 22, 2023 | 0 | by Morgan McCarthy The state of Wisconsin is asking people not to feed the deer in the winter. The Department of Natural Resources yesterday asked people not to leave corn, alfalfa and other feed in their backyards. Biologists at the DNR say feeding deer in the winter can actually hurt, or even kill, deer. Feeding deer is actually illegal in most Wisconsin counties, and there are restrictions in the few counties where it’s not.
