This would now be our third family of hens and rooster (currently, six hens). We have a great; safe and healthy coup with six hen boxes that are clean and padded nicely. With that said, each family of hens, over the years, has ALWAYS used only one of the boxes oftentimes with squabbling from the other hens when one hen takes her time sitting in the box until she produces an egg. We have tried different ways of enticing the hens to use the other boxes, to no avail. Again, this happens with each family of hens. Anyone have any ideas why this happens and what I should do?
