So I am really struggling with this cold. I know a heated coop is not good. I know ventilation is vital. And dry as well. But I just cannot handle that they are in negative temps during the night 
So I finally caved (shocked it took so long!) and bought a panel heater. Not enough to actually heat the whole coop and I believe much safer than the other heat sources. My rooster is getting some frostbite so I decided it might help take the chill off and placed it next to his roost.
I'm literally inside the coop knocking my head, frozen toes and fighting off the curious chickens wanting to peck at all the new shiny things installing them (because 2 is always better... right??) and really struggling. This is usually hubs job but he is traveling for a few weeks.
Success!! The coop is a consistent 5-8 degrees warmer overnight and staying dry. I was so proud
Well, the older gals decided to stay outside still but that is what they prefer. But the rooster and two pullets were inside. I bet they were loving it, for sure!
Second night I head out to tuck them in and all but 1 pullet is outside. WHAT??
Now tonight ALL birds are roosting outside!!!
Seriously?? They must hate it!
Why do I even try?? It's like the water, as sure as I supply multiple clean water dishes they will find the nasty dirty rainwater to drink.
The struggle is real.......
I have to add that I installed 2" foam insulation board along the west side and SW corner to help with crowing but it has made their outside roosting area quite comfortable. And I didn't even have to climb in the coop to do it! Sigh.....
