Everything I've read and seen in real life says I'm at least partially right. Moms do shuu the little guys away when the bucks are courting. The buck fawn from the previous year will get reaquainte with mom usually during the year and is often seen following her and her new fawns in late summer and spring. When the big bucks start getting antsy the next fall the little bucks are run off by the bigger bucks. The fawn that mom chases away is right back with her by the time the rut ends. I've read this in numerous articles by "The Experts". I've seen them with mom all summer during crop damage hunts. I found some reference to it on the web, but not what I was looking for. Here's another squirrelly look at it from a different point of view. They say some of what you say, but not exactly. http://www.thejump.net/Hunting_Articles/manage.htm
