It has been below zero here lately and I keep a radiator heater in the coop. What are the Pros and Cons of heating?
Pros....
The obvious....warmth in the coop. This does not, however, translate into more comfort for the flock....they have developed winter coats for cold weather, so heating them can possibly cause them to discomfort from becoming too warm. Try wearing your winter gear as you sit in a warm room and see how uncomfortable you soon become...you start to sweat, then that sweat will make you colder once you go outside.
Can keep water from freezing
Cons~
Potential coop fire
The birds have difficulty adjusting to the heated environment of the coop as they move in and out of it, causing them to become more chilled than normal when going outside
Increased humidity in the coop due to overheating of the chickens, causing them to throw off humidity.....the heat of the heater may or may not dispel this humidity...usually people who install heat also will close off any ventilation in an attempt to conserve the heat in the coop.
Increased utility bill
