Hello all - total newbie here. We have just 4 chickens, about 6 months old now (no eggs yet), and I'm starting to wonder about heating our hen house. We live in zone 3/4 and while the late fall has been fairly mild, it is going down to the teens tonight and winter will be with us till late March. I know I need to insulate the water to keep it from freezing but what about a heat lamp for the hen house? If so, how many hours should this be on and can anyone recommend a certain type? The chickens are Buff Orpingtons and supposedly fairly hardy for our climate. I'd greatly appreciate any adivce. Thanks!
