Well, we are just getting the coop wired so this has opened up our options considerably! We are re-insulating the inside this summer.
I have seen many coops around here that use baseboard heater mounted about 2-3 up a free wall, so are thinking of trying that. Also, continue to have the heat lamp above the roost. One person I know is trying an infrared light instead and we may look into that.
So, far that is our plan. It keeps evolving as time goes on but I think this year if we get it insulated and some baseboard heaters up we should be good to. I know some ppl discourage against them but I think it's the best option for us as it gets really, really cold here ( like -40C over night...I guess that would be -40F!!! Wow did not know they would be the same!!...thanks online conversion!!lol)
What do you have or plan to have?
