So, my 8 week old pullets have been in their coop & run for about two weeks now. They finally started going into the coop at night on their own once I put a light in the coop for them before dusk. I don't want to mess with their circadian rhythm, but prior to their night light, they wouldn't go in the coop on their own. Any suggestions on how long to keep using the light? We don't have electricity in the coop, so it would be hard to put a light on a timer.
