It gets pretty COLD up here. Jackie has a huge comb so shes the one I always worry about getting frostbite. All my other chickens have little combs. I hope your roosters don't get frostbite.That's cold! Chickens can get frostbite if it's any degree below 32 (Fahrenheit). I'm worried about my roosters though, they are all single combed and will be very susceptible to frostbite :/ Since it got down to 19 degrees and has been snowing, I need to keep an eye on them.
