can you get some straw or hay bails to put around the outside run perimeter to block wind at ground level? put a layer on the run floor, chickens love scratching in it.I just coaxed them back outside and goldie ran right to the nest box she did NOT LIKE the square bucket w bedding n fake egg i set up in the kennel. She squawked at it knocked it around and kick the egg axross the floor lol. I leaned plywood on 2 sides of their prefab coop run to block wind. Not sure what else to do for them. I feel really bad to get them accustomed to 50+ degrees. I didnt know. Many posts talk about larger flocks doing OK because they can huddle together. Mine 3 hens free range my fenced in yard most of the day, so i never built a a bigger run. I dont have a heater that will work outside in these temps, just small bed room heaters. I have a heating pad i could run and extension cord to their coop? But is it a fire hazard, how do i know if they hate it. I can put it on the floor, dont care if the poop on it maybe?
