I know the recommended starting point for ventilation is 1 square foot per standard size bird. This is only a starting point because there are so many variables, so if we start there, we can add or subtract some ventilation as needed. Some of yours are not standard size, and I'm not sure what the recommended starting ventilation is for them. Someone else can probably help you more with the needed ventilation. But if you have as many birds as your signature shows, you very likely don't have enough.
If you see condensation (water droplets) on your walls or windows, this is a strong indication that you don't have enough ventilation. Also, if you can smell ammonia or other bad odors in the coop, that is another indication.
Will someone who can help, please help her with the ventilation question? If we don't get any other help here, I'll start a new thread for you.
