I was thinking of putting some outdoor plants that have a slim shot of lasting through winter outdoors in my chicken coop....not in with the chickens themselves but the storage area....I thought the few extra degrees will ensure their survival....but might they create too much humidity with watering? And will that make it harder on the chickens? I'm sure I can find an alternative, but if this would be a win/win, making the air quality better with the co2/oxygen, that would be great.
