What is the safest way to heat a chicken coop? I don't have chickens yet, but I was just wondering for next year. Would a microwaveable heating pad even heat the coop at all? I was thinking about using that, but it might not even change the coop temp. Have any of you tried this, and if so did it work? I know that I don't have to heat the coop, but I want the chickens to be happy and warm on cold winter nights. Any suggestions on what heat source I should use?
