Great and informative article! I personally use hay for bedding in the nest boxes, the females prefer the use of hay rather than any other bedding. Unfortunately, even though they have plenty of roosting space that is not nearby the nesting boxes, some hens still sleep in the nesting boxes for some reason. The article states that it is a hard habit to break, and I personally have never tried to stop them from nesting in the boxes because I do not wish to stress them during the night, and they will just go right back to the nesting box anyways. I believe there should be a section in this article that gives tips on how to get hens to stop sleeping in nesting boxes!
