okay so home depot has ceramic heaters on sale for $20 every tells me they are really cheap to run but wont heat a large space so here was my thought. Would one work in my coop to keep the waterer from freezing and the girls happy this winter. I need to look into them a little more and see if they can be set to keep a temp of like 35-40 , just enough to keep the water from freezing. But the way I am currently looking at it they have to be cheaper to run then a heat lamp over the roost and a 60 watt bulb in concrete blocks under the waterer to keep it from freezing up. What do you all think is this crazy or could it actually work?
