I use a golf ball but I have white eggs. If mine start laying in the nest furthest away from the door, I'll put the golf ball in the first one and they will start laying where I put the ball, at least for a little while after I take the ball away.
Mine always try to use the same nest unless it is too crowded. I have seen them really packed in there instead of just using another nest.
