Anyone else in Arkansas worried. We're expecting tonight and tomorrow, wind chills down to MINUS 20, northerly winds gusting around 30 mph, and tomorrows high is 19. They've handled the weather temps so far alright, though I did see 4 hens in one regular sized nesting box one evening. They're still getting around during the day and no signs of frostbite. But this drop tonight is going to be the lowest temps we've experienced by far. If there was snow that would help insulate their henhouse, but it's going to be sleeting rain and ice and a hard cold wind....they're in an insulated fancy dog house, but still worry, still cracks and crevices for wind to get in. So far I've been keeping their coop door open at night, should I shut it tonight....let them sleep in the bathroom...I'm so worried about my girls! I have no way to hook up heat for them, no electricity outside. Any advice is appreciated. This is my first winter with chickens
