Frequently asked questions
Do chicken coops need to be insulated?
Helpful in cold climates if dry. Critical to combine with TOP ventilation so moisture escapes, sealed insulated coops cause more frostbite than uninsulated ones.
Should I heat my chicken coop in winter?
Almost never. Cold-hardy breeds tolerate -20°F. Heat lamps cause coop fires and de-acclimate birds, if the power fails on a cold night, you lose the flock.
How do I prevent frozen water in winter?
Heated base for plastic waterers (~$40), heated dog bowls, or rotate two bowls (one inside thawing while the other freezes outside).
