Yeah, I've seen that in my own handful of birds. Only those with larger combs get frostbite. A little Vaseline on those combs once each day can help prevent it, and save the bird some pain and stress.
I'm not exactly in North Dakota or Fairbanks Alaska, we only get a few nights below 0°F per year, and maybe only one or two weeks with daytime highs in the teens°F, but my chickens have never had any issue with cold.
Our summer heat has killed a few, but that was my fault for buying a breed specifically known to have issues with heat stress. Choose your breed(s) according to your climate, and there's really no need to worry about cold or heat.
The story above about the barn fire is even more common among coops. We had a family member with a coop burn down, and there are numerous stories over at the Backyard Chickens forums of coop fires, due to heating systems or associated extension cords.
