I decided against a flat panel heater because most of the reviews I saw (on Amazon) said that it didn't work well when installed on an exterior facing wall. Well, that's every wall in my chicken coop. However, there are a few BYCers who have flat panel heaters. I suggest doing a search (see the blue bar above) and see what you can glean from others' experiences.
And just for comparison sake, I have heat on 24/7 in my coop from October through March/April and my coop averages around 10-15F. So yes, chickens can handle quite a bit of cold and still thrive. Ventilation is your friend.
