The answer is an emphatic "kinda". Though most bucks have shed by late March across whitetail range, there are plenty of exceptions. Easy winters and plentiful food result in unstressed bucks that tend to hold antlers longer. But even when the winter is tough, some bucks are just late shedders. I've known several guys who've kept captive deer over the years, and they all note that when bucks shed can be a highly individual deal. One buck shed his antlers within 2 days of February 25 every year, regardless of conditions!
