@Dreamzchaser, my very first egg was laid in the run. The second one was in the coop, near the pop door. I put a board over that spot, and the next one was just farther down the wall. Here's what I did that fixed the problem.
My nest boxes are 18" off the coop floor, and inside. I took one off the wall and put it on the floor where the egg was laid near the pop door. I put a couple of boards on the floor down that wall, so that they wouldn't just keep moving to a new area there. Except for a couple "oops" eggs from the roost (common in new layers, I guess), all the eggs have been in the nest boxes from then on.
I started putting bricks under the nest box, raising it up a few inches at a time, until it was almost back to the original height. Then I just reattached it to the wall.
