My coop is pitch black until I open the door. They don't make a single buk or bawk until I wake them up. I do hear them talk very quietly in their bedtime voices/calls. Having the coop pitch black helps. They don't start their racket until a half hour to hour after I wake them up. The ordinance says 7am-10pm is when hobby farm noise is allowed. My coop is also fully insulated, so it helps keep the noise level down when they are inside. I usually throw two handfuls of homemade scratch and that keeps them busy for a while too. If I let them out of the run to free range, they are quiet then as well. On hot days I do open the door early around 6 am. Good luck.
How do you make your coop pitch black with ventilation?
Another crazy idea, if you have to close your coop ventilation...can you put an air purifier in the coop to help with ventilation? I know they make the air humid, so not sure if that would work.
