Here's the way it works...
Does separate from their extended family groups to fawn in early summer. The mothers and offspring spend time alone until around the time the spots come off the fawns. At that point, doe groups begin forming back up again. Does that did not have fawns or does that lost fawns will group back up with each other earlier than those does with fawns. As does come into heat, they break off from the family group and their fawns to be bred. Her fawns will try to stay as close to mom as possible, but often young bucks chase the mother farther and faster than the fawns can keep up with. After breeding, the doe will go back and rejoin her fawns.
After the majority of does have been bred, they form large extended family groups in December. Button bucks have usually wandered off by now, but a few will still remain in the extended doe family group until spring. And then the process repeats itself.
USUALLY, the first does to come into heat each year are the adult does that do not have a fawn. Their superior body conditioning in late fall allows them to ovulate earlier. This is followed by 1.5 year old does (without fawns), then adult does with fawns. Very few doe fawns come into estrous on my farms at all their first season. By realizing where you are in the rut cycle, and knowing which does use which areas, I've found that I can target the adult does without fawns and use them to get to the older bucks before other hunters. Later in the rut, I focus on the does that I've seen with fawns earlier in the season. Works pretty darn well.
