The move itself usually doesn't stress them to abort. I have moved does as close as 3 days before fawning, but it was tame does that were loaded without any real stress. The ride was only 1 hour, and all did fine. If you have to tranq, the rule of thumb is do not do it less than 30 days before fawning. Having said that, I have tranqued a few does on an emergency basis 7-10 days before fawning and they did well. I wouldn't tranq unless it was an emergency.
