I have 9 hens. The chickens free range during the day and then historically have returned to the coop religiously every evening before sunset. A few weeks ago a few chickens did not return to the coop. A week later none of them were returning to the coop. They are choosing to roost in the back of my barn instead (and laying eggs randomly all over the barn). I have manually returned them to the coop, but have grown weary of doing this each night. I'm about ready to give up on them. The coop has every creature comfort they could want (shelter, roosts, nest boxes, food, water, supplementary heat when very cold, etc.) so I don't understand why they are not using the coop? Does anyone know how to get them to start going back in the coop at night and laying eggs in the nest boxes within? Please help! Ryan in Eagle, ID.
