Yeah, chickens have to be related to Yeti, because they really don't mind cold like mammals do.
The only time I worry about my hens is when it gets below zero. And even then, I'm sparing in what I do (I want to encourage them to grow their own protection). I'll heat up a brick in my oven and put it into their coop around midnight. It'll radiate heat and bring up the temp in the coop about 10 degrees or so without acclimating the hens to constant heat. Also, I live in fear of electronic heating sources catching my coop on fire
