I have 14 mixed flock of EE,RIR,BR chickens. Large coop with 6 nesting boxes, three on bottom ,three on top. They do free range all day, but all but 1 come into coop to lay. They fight over the bottom three. I have golf balls in the top three, removed the golf balls from the bottoms, in hopes that they will take an interest in the tops. No luck. I had to add some old crates to make three more boxes to lay in. How in the world can I get them to lay in the top nest???? And yes I have picked them up and placed them in there a few times, they move things around but never stay and lay.
