We are new the chickens this year. Our coop is relatively close to the house (so we could babysit them and try to keep predators at bay), and it doesn't have electricity out to it. We could concievably run an extension cord to the house for the winter. That may be enough for a heat lamp. Can one of those be on all night safely? Is there a better solution? Right now we have a stick up fluorescent light to check on them in the dark, but there is nothing set up for warmth. How cold can chickens get? How do I keep them warm without setting anything on fire? How do I keep water unfrozen (besides changing it several times a day which is what we are planning now)? Any other people in places where there is real winter who can give me some tips?
