I want to get a humidifier so that maybe it might help with the winter dryness for my birds. I don't know which one would be okay warm air or cool air. I spoke with someone at work about it and they said that one of them causes mold and spores which I think is bad to have, but not sure which one and which one would be good for my birds? Can I get opinions about humidifiers, warm air or cool air?
