Deer ALWAYS have more than one bedding area. It is there instinct to change bedding areas all the time. Reason for this is to prevent an ambush of a predetor. Think about it. If you returnedto the same bedding area day after day, leaving your scent at that spot, wouldn' t you think a predator would be there waiting for ya??
Some deer bed in a field, to tell if they do or not, look for grass that have been layed on....It will be flattened and in an oval shape.
In the woods, look for a REAL thick area of bushes or weeds. I usually jump them out thick areas leaving a new hunting area in the middle of the day

. Also, if you see deer poop in the area, bedding area is close. Deer only poop in places they are safe, and only bed in a place that is safe aswell, so thats a good sign.
Good Luck!
