Some times, deer will start losing there antlers as early as December. It all depends on when they are ready. The cause of most antlers to shed, depends on how much late season sparring a buck will do. Bucks sparr with eachother after the rut to help loosen the antlers and to develope the pecking order. I would have to say that most shedding though, occurs from late January to sometimes early March and even into April on some occasions in my area.
