Well, it is getting pretty cool here in Montana! This will be my first chicken winter. I have a coup that is made out of 1/2 my tool shed. It has a cement foundation, electricity and a window. I am wondering how I should winterize. Should I insulate the walls or the door with anything? The door is just a hand made thing out of OSB and 1x4's. I was planning on covering the window with something. Also, should i put a inferred heat lamp in? Would it go above their roost? When would I have it on? Wow- i sure will feel bad for them this winter when we are nice and toasty inside with our wood stove and hot tub! When do you other northerners start to winterize?
