Hello CCx6, thanx for the suggestions, right now, I have a little Holmes Ceramic heater inside, as I am working on the inside of the coop. I have it truned down to the lowest setting, and it is keeping the coop at 35-40, with an outside temp of 20. I obviously cannot use this inside with birds and shavings, at least not on the floor, but I might try and make a cage mount for it, and clean it every week with air from compressor.Just a thought...
I have seen ceramic heat bulbs that work in the existing sockets used for the red and clear bulbs. Not sure on reliability.
Perhaps an oil heater? They do not get as hot and are a sealed unit rather like a radiant heater for old homes.
I have 2 just in case we get below 0 here and I am in Colorado.
I may not need it but feel better having them even if we do not get that cold.

Last night a quart of water about 1/2 full froze solid in this insulated coop, it is empty and no heat source.
I am not keen on brooder lights, but may go with an oil filled rad heater., as you have mentioned.
Here is the coop 6ft X 8 ft X 6 ft ceiling.still getting things ready, no vents yet, gonna house 5 bantams in this coop, they are in my garage right now, with temps around 40....RR
