Ok So I've got 16 laying hens. 12 nest boxes in their coop with them. Not all 16 lay everyday since some of these are bantams. But They always lay in the bottom 3 nestboxes. Sometimes on a rare occasion there will be a single on the next level up on the left side but otherwise nothing there. There ends up being like 5ish (give or take) eggs in each box. So why do they all lay in the bottoms ones, is it because they are closer to the ground and feel safer that way?? I would think they would use the empty ones, but I guess not. Any way I can get them to lay in the upper nest boxes too?
