Now that it is warming up and my neighbors will most likely have their windows open I need to find something to muffle the noise from the chickens in the morning at the crack of dawn. Is there anything out there that will provide ventilation and keep the noise contained? Or maybe if I just keep the light out of the coop? Maybe shade cloth - would that darken it enough that they still think it's nighttime? Or do I just need to resign myself to letting them out each morning at 5:30?
