Does anyone know of a way to stop my two roosters from crowing so early in the am? They start around 4:30am and are disturbing my husband's sleep and my neighbor. Would locking them up in a dark place keep them from crowing until I let them out? Does anyone have a solution. I don't want to rehome them or kill them or anything like that. I just want them to not crow until at least 7 or 8am. Thanks for any suggestions!!!
