I have a flat panel heater in the henhouse that comes on at 0, goes off at 10 degrees. It heated the henhouse from -24 last year to approx. 7 f degrees. So it does not heat to 50 degrees, if the electricity goes out, they will be fine, they are acclimated, this just takes the edge off in extremely cold weather.
-In the run, if needed (someone is molting, or below -10 degrees) I'll turn on a heat lamp. I have dirt/sand below it, no shaving.
-It is zip tied to the pen.
-I have a cage made of hardware cloth over it, which I truly believe is needed. It keeps feathers from flying up, hitting the bulb starting on fire and dropping into the bedding. or a wing catching fire and, and...
-Also my last bulb fell out of the metal holder, yes, it can happen. luckily my "cage" caught the bulb thank goodness. photos below.
