I love this website! We live in a small city in upstate New York and got baby chicks in the spring. Now we have 5 Lovely hens who I hope are ready to start laying soon. My question is: we have built into a room at the back of our garage. Early in the morning my hubby carries each girl out to a PVC run that we Move around the backyard so they can forage. At night we out coop them again when we get home from work. There are nesting boxes in the coop, but not in the PVC run. Do we need to make boxes so they can lay during the day? Would enclosed kitty litter boxes work? Thanks!!!
