O I believe it. I see -40 often, especially when it gets to be Jan-Feb. That was the reasen for my first post. I wasnt sure how hardy chickens were and wanted to make sure that they were going to be warm enuph. I plan on picking up another heat lamp so I have 2 in there but Im going to get timers and try to run it where at around 4am a regular light will kick on and stay on till around 8-9am depending on what time the sun is coming up. I plan on having 1 heat lamp on in there when it drops down to 0 and then if it drops down to -30 or colder depending what the temp is in the trailor I would have the second light to help if I need it. But Im hoping the one light will do. Only reasen Im using the regular white bulb is so they get enuph light to keep them laying well.
