i need to get something to heat my coop for those nights where it gets in the single digits and less. my coop windows face south so they get sun almost all day in the winter. i've been looking at heat lamps but i am weary of a fire if they knock the lamp down. if i get a heat lamp what size bulb and what type red or infared? i was also wondering if they sell a 125watt or less bulb as that would seem to be a bit safer than 250 or higher. i've been also looking around work for an extra bucket heater, which is a heater for the "bucket" on an aerial lift truck, think electric company, they are a small sq box which uses forced hot air kinad like a hair dryer if i can get one i may mount it on the ceiling and build a duct to make the warm air flow down.the heat coming out is also adjustable. any other thoughts on usable heat sources would be great. thanks jim
