My first egg was found today and it was NOT in the nesting boxes, it was at the very back of the coop where I had difficulty reaching it. So in my attempt to get my hens to lay in their nesting boxes I have added golf balls to the boxes to show them where to lay, and I also added privacy curtains to their boxes. I made the curtains from burlap. I cut the burlap into strips to cover the front of the boxes to shade the light & add privacy. From what I've read hens like to lay in areas that are secluded and away from light sources. These are both tips that I have seen/read online. I'm new to chicken keeping, so I'll see how this works. Thought it may help some of the other new back yard chicken keepers.
Update: IT WORKED! The very next day I went out to find an egg in my nesting box.
I found an egg outside the nesting box at the back of the coop this morning but I think it may have been there before I fixed up the nesting boxes with the golf balls and I just didn't see it, because this afternoon when I returned home from work I found another egg in one of the nesting boxes.
