Hello. I started a new flock last spring and my ladies are happy and adorable. My only issue is that they sleep in the nesting boxes and never use the roost installed in the shelter portion of my coop. This is my second flock and the previous flock (living the rest of their lives happily in a nearby farm) used the roost immediately when introduced to the coop. Only thing is, I got the old flock as adult hens, so they were already roost-trained, if you will. So, now that my ladies are 9 months old I am not sure how to get them to start roosting at night. I also tried lowering the roost to make it more noticeable, but so far no takers. Is it too late? Should I block the nesting boxes to force them to find another place to sleep?
