Let me know if this will work. I am going to use a thermo-cube on/20 off/30. Put one of those in the middle mounted to the roof. Was going to bring water in the coop and put it under the light. I know 30 is below freezing temp for water but was thinking with the light shinning on the water it would melt and not freeze. I was loking at porclein light and they seem real expensive. Would a heat lamp or IR light put too much lite out and bother the birds at nite. thank you, this is my first winter.
