I have two hens who lay have been laying every day for a couple of months. They both lay on the floor in the hen house, not in the nesting boxes. They usually lay in a clean spot, but I would like to encourage them to lay in the boxes. I have put golf balls there and they just knock them out when they sleep (as they seem to be sleeping in those lately and not up on the roosting bars) or ignore them all together. Is there any reason they might be laying and sleeping in the "wrong" spots and is there a way to encourage them to change their habits? Or is it no big deal?
