I'm looking for suggestions to keep the coop dark but having good ventilation at the same time. We tried to make the coop dark, but at the same time we found the ventilation isn't as good and our girls are probably not happy about it. Any suggestion would be really appreciated! Our house and neighbors are next to each other. We really need to keep our girls quiet in the early morning. Reading the forum and found keeping the coop dark is the best way to avoid the morning calls/egg songs?
