We have 7 young hens, that have recently started to lay. there are 7 hens, and 4 boxes for them to use... the issue is that they all seem to lay in just one of the boxes, occasionally two... the row of boxes is against the coop wall, but the one they all like is in the corner, where the row of boxes meets the next wall. They disrupt each other when trying to lay, even crown 2 into that specific box.. and the dominant hens we think are plucking the feathers off the others heads. solutions? thanks!
