Because they're chickens not people 
They really do not get frostbite (in dryish, draft-free air) at freezing -- they produce body heat and their circulatory systems are fairly well designed.
I mean, look at "real" birds (cuz remember, chickens ARE birds) -- wild turkeys and crows and goldfinches and what-all do not get frostbite at normal winter temperatures.
Realio trulio, in dry draft-free air with a properly managed coop, most chickens are good down towards 0 F and many will be fine much, much colder than that.
Also remember the coop temperature is usually a bit warmer than outdoors on cold nights.
Good luck, have fun,
