You may be able to set up 2 stands without messing things up, maybe 3. I would not set more than one a day though and give it at least 2-3 days before setting the next. Start at one end of the property and set a stand, wait 2-3 days and set one at the far end, then 2-3 more and set one in the middle area.

The lay of the land is important, you may only have one spot in the whole 15 acres that will be a good place to put a stand, you may have many more, it is all determined by the lay of the land.
