I am inersterested in BYCers ideas and remedies they use to keep chickens with large single combs and large wattles from freezing over winter. Since I don't have a heated barn and live around the KCMO areas, I am open for suggestions. This will be the first time that I have single comb birds over winter. I ususally raise wyandottes and brahmas, but was able find some excellent show quality large fowl black cochins this summer and I would hate to see their combs froze. Looking forward to reading your remedies.
