I believe I posted before on the old thread, but another Northern Indiana resident here.
I do more "trolling" than posting.
I have approx. 25 chickens. All different breeds (I like to experiment).
Winter so far has been OK. Our coop is pretty well insulated, but one of my roos did get some frostbite on two of his comb "peaks". Not sure how concerned I should be considering we haven't even hit the coldest part of winter yet. We didn't have any problems last winter, but it was a really mild one. Since this fall we lost 2 birds (one bantam, one full size) to hawk(s) and one bantam who just never came home one evening. Of all the birds I'm only getting bout 2 eggs/day right now. Bummer.
Where are you in Northern IN?
