Bucks here in Iowa normally drop during Feb - Mar, but due to the extreme weather this year (tons of snow and abnromally cold) they dropped really early. Friends who muzzleloaded two weeks ago shot 10 "slickheads". When they went to the deer, they discovered 6 of them were bucks that dropped their antlers. They told me they thought it odd they had not seen any bucks while hunting and were sick to their stomachs they dropped six bucks without knowing it.
