My first set of chicks would not go into their house at dusk. They would perch nearby and wait for me to put them in and shut the door. I moved them to a larger coop and brought in another set of chicks expecting them to do the same thing. Then it hit me. I bought two cheap battery powered LED lights for inside both houses. At dusk I turn them on and the chickens move right in with no problems. I couldn't believe it. Turn the light off, shut the door, easy.
