I have seen, in January, a very small doe with several buck in toe. One instance was two years ago I was driving near my home and spotted a buck in a power line. I turned around to look at it and saw a total of 7 buck all trying to work this small doe. She had to be less than 100 lbs. She was just standing there while all these buck were lurking. It was as if she knew if she moved an inch they would all dog her again. I think fawn doe get bread more than you think. JMO.
