Sheds tend to be found in 3 areas, bedding, feeding and travel corridors. Deer use different bedding areas in the cold winter/spring months than in the summer, so look for south facing areas that have fairly thick cover. The south facing slopes get more sun and the brush/trees cut the wind which reduces the energy expenditure of the deer. It's best to wait until spring hits to look for sheds as the deer are quite stressed this time of year, mostly from the rut and cold weather, so hiking around pushing them out of their "living rooms" can put an undo demand on them. Some unscrupulous people deliberately push the deer hoping their antlers will fall off in flight, so be considerate of the resource and wait 'til it warms up to start looking.
