I live in Northern Florida but last winter we had quite a few very cold Days (okay stop laughing) On those very cold actually below freezing (yes it does freeze here) days, Someone posted about using a 5 gallon bucket with a lid and hot water to heat the coop. Well It worked fabulously. I loved that it provided heat and I didn't have to plug anything in all night and day. I got the buckets for free from Winn Dixie, Publix and Walmart from the Bakery Department (just ask...they toss those frosting buckets if you don't ask for them) I did not have to worry about fire or electrical shorts in my coop and my chickens were cozy and happy. I also invested in a can of bag balm and used it liberally on the combs, waddles and feet. They enjoyed the attention and it helps to prevent frostbite.
