My coop has a 4ft long community nest box. I have six chickens, only two of which are laying, and they both lay right next to two golf balls I put in there to help them know where to lay. That's in the back corner of the right hand side. So this morning, I moved the golf balls all the way to the other side to see if they'd lay over there. When I came home, I found the two eggs in the right corner as usual...as well as the two golf balls! One of them pushed those things 4 feet to get them back where they "belong."
