I'm getting ready to upgrade my 4ftx4ftx4ft to survive the winter. Right now it is just wood with no insulation whatsoever. I'm wondering what can I do to keep my bantam wyandottes and my standard leghorn pullet warm and cozy during the winter? I was thinking about putting a piece of cloth or something in the pop door to keep heat in while letting the chickens in and out to the run as they wish. I was wondering about the run aswell. Should I cover the runs sides with a tarp or plastic so the chilly wind isn't blowing on them? Is there anything I could spread on the ground so there feet are off the cold ground? Please give me some ideas! Last year I kept my 2 standard leghorns in the basement. Another question... Where should I put a heated waterer?
