After all my endless discussions online and fretting, we have succumbed to the heat lamp. I have only used it a couple of times but will use in on Sunday night. The roof of my coop is open, but there have been times that no matter how open the hen house is - the humidity is in the 70-80% and frostbite is inevitable . . . so far - very minor - just unsightly. Humidity should be low, so that will nip frostbite - but since my coop is open, we will plug that heat lamp in (after a close inspection for dust and security). Even with the lamp on, most of the hen house hovers around 10 degrees when it gets that cold. But in the end, I sleep better at night. It's not so drastically warm that they'll be shocked should the power go out. . . I hope. They also have an open door, so I'm hoping that if - in the event of a fire - they will know to head out the door to safety. :cd -(fire!)

One of my RIR hens got frostbite awhile ago and now one of my White Rock hens has it.
