We have been discussing methods of heating the coop during the cold weather months and some have recommended the use of bottles of hot water. I was out in our barn yesterday and there was our old propane turkey fryer with the 30 qt. aluminum kettle. I think the 30 qt. kettle would do a great job of keeping our little friends warm through these very cold times. The burner and gas tank could be set up inside the coop if there is some available space and then the kettle of hot water would not need to be carried to and from the coop. I think I would make sure there is adequate ventilation when the burner is turned on. Or the burner could be used just outside the coop. The water could be re-heated over and over again. And the lid could be strapped on to make sure nobody becomes chicken soup during the night and to keep the humidity down. Any comments?
