-12 projected for Tuesday. How concerned should I be about my flock of four? They are in a hoop house that is covered and very protected from the wind but uninsulated. They do have a small coop they can get into within the hoop house but it too is uninsulated. Should I be bringing them in by the woodstove or just let their downy feathers protect them? They seemed fine when we got to neg. 3... First time chicken mommy here, can you tell?!?

, we have hunting dogs, so they wouldn't last long in the house, yikes! Besides my hubby wouldn't be keen on it either. I will put some extra bedding down as well as some hay as suggested! Thanks so much for all the responses.
my sissies won't even think about walking on the snow. They look outside and just shake their heads at me! Not gonna do it.
