I have never seen a deer scrape the snow away. Measure the bed. big bucks make big beds. Check for tarsal stains. check for horn imprints. a bed with a stain and a bed w/o. could mean a buck w/a doe. might be worth a track job. Big bucks tend to sprawl out making a bigger bed. Check the age of the bed. are there older ones the same size?- maybe a clue of a big bucks prefered bedding area.
