This is my first year having chickens and I was very worried about the cold.
After reading through your artic weather thread from 2013... pretty much, the only thing I'm worried about is frostbite and critters, lol. We have leghorns and their combs are bigger than your what your breeds are.
That doesn't mean I'm not winterizing, lol.
Just that I'm no longer concerned with extra cords, heaters, bulbs, etc. Right now, we have one cord and it's going to be used for a heated waterer, outside the coop. And we're putting up clear shower curtains on three sides...

Anyway...I would tell anyone who is worried about the cold effecting their chickens to read it. If I knew how to link it, I would

.
Of course everyone's set up is different, but for my small coop, it really eased my mid. Thank you so much for taking the time to record your experience.

I'm also new to the site & didn't realize you were still active.
I was going to say something on your thread, but because it was older, wasn't sure if you'd see it.

(shout out to
@biophiliac for recommending it to me).
I think I remember that winter, we had around the same temps. I'm in a small valley, south of Buffalo, NY, right in the snowbelt. I'm pretty sure that was the year we had windchills at -62F!
