I realize I probably don't need a heater. I live in North Carolina and it doesn't get terribly cold But, I'd like to pamper my 5 yearling peacocks. They've taken up roosting on a deck rail beside my bedroom. I'm currently building a roof over that rail. Does anyone have suggestions for a low voltage heater, to further help them over the winter? I've looked at weatherproof dog beds, but they heat to 110 degrees (overkill) and would probably run the electric bill up I also looked at decking steps (heated). They are low voltage and only intended to keep snow from forming. That might be perfect.... Anyone have suggestions? Something easier, or cheaper, or a method that has worked for you? Thanks.
