No matter what I do, my 13 chickens, when they lay, all lay in the same box. We have 5 boxes, the corner box is their favorite. I have tried moving eggs to other boxes, using ping pong balls, making the corner box less comfortable, but they still leave a pile of eggs in the box. Today there were 12 in the pile. My only concerns is that when a chicken jumps into the box they will break one, eat it, and find out the reason we people loves eggs and then start enjoying themselves.
