My friend had the same problem and tried top of locking them in the runs and it didn't work. She then put herbs in the nesting box (they sell them to put in the nesting box or make your own.) and it seemed to have helped. It took about a week but now they lay in the nesting boxes.
When I have to lock my girls in, I have a water bottle with small holes drilled in. I put treats in it and they kick it around to try to get the treats out. It occupies them for a very long time.
