Fawns will generally lose their spots in Sept here. But there have been known cases where some hold onto them through Nov. The rut in Wi usually starts about the first orsecond week of Nov. During bow season I see fewer deer the 3rd week in Oct, this being what I have experienced since I started bow hunting and believe this is the lull. The the last week of Oct the deer come crawling out of the wood work when the seeking phase kicks in.
