. Great to have you with us. Lots of folks stress the winter but it's actually summer that's tougher on chickens than winter - even a Minnesota winter. Take it from a Kansas guy who saw the temp get to 94 today! Wouldn't mind a little winter right about now. You'll have to find a way to keep their water thawed but other than that, a draft free (but still ventilated) coop - even unheated is all they need. I have an uninsulated tin coop and, while I know KS isn't MN when Old Man Winter comes knocking, we still touch -10 on occasion - and that's without wind chill. Chickens are little furnaces that put out a surprising amount of body heat and with enough of them like you have, the coop stays, if not toasty, at least livable. Now all that's not to say a little winterizing isn't good thing.
