Personally, I don't let my birds out in the snow, Period. Its too cold for them. The closest they get to being outside is their enclosed Hutch. On a good day I will open the flap so they get some sun but that's it. My hutch during the summer, in front is the coup. Hutch is tarped and sealed in for the winter, a recent blizzard did that. This is the side with the flap I can open halfway. Below the flap is open. Inside the insulated coup is a low roost one of the co-op's is on, a higher roost for the turkeys that the chickens also use and the nest boxes they pile up on. They even have a feeder just above the boxes and the coup is well strawed to retain the warmth. There is a little door under the boxes that is opened from inside the hutch that leads out from the coup to the hutch. Amber is demonstrating the higher roost and you can clearly see the little door under the boxes. Pile up on the boxes! Help for frostbite: I'll be getting some of this on Thursday!!! I'm careful to keep my birds protected and warm, the alternative is too horrible to contemplate.
