Is there something in a hen that makes her want to go into the nest box to lay. I have 7 hens and 3 nest boxes. I placed a golf ball in each nest box which was recommended here at BYC. The hens are now 19 weeks old and show no sign of being in the boxes. No feathers, poo and the bedding stays as neat as if I just placed it there, never dirty. I am wandering if they will show interest when the time comes. John
