I have my chickens in part of the barn. It gets cold out there and the water is already starting to freeze. The barn in about 150 feet away from the house. Do you think I could run heavy duty extension cords to it and use a heated waterer to keep the water from freezing. I would need to plug it in from the other side of the house so I need about 200 feet of extension cords. I dont want to start a fire. Thanks for your help.
