This is my first winter with chickens I have 4 hens and 4, 5 month old muscovies. I have a 3 1/2 foot by 5 foot coop, that is not insulated. I did wrap the coop with a draw string tarp. I read a lot in the forums and decided not to heat my coop this winter, My coop has small vents up high and is pretty draft free. BUT the winter here this year has come very suddenly, it was 30 degrees Fahrenheit at night fall, and yesterday night It got into the teens. Thinking the sudden change might be too much for the first timers I broke down tonight and decided to put a mini crock pot (a bit larger than a soft ball) In the coop. Has anyone ever tried this before? Does this sound like a safe source of heat. It is sitting on a plate with a large medal bowl over the top. I cant think of a reason this would be a fire hazard, Can you? The crock pot has only one temp witch is hot to the touch but not so hot it can hurt you. The medal bowl is warm. I have been checking the temp inside the coop last night got close to 10 degrees and the temp in side the coop stayed around 30 degrees. I am not planning on having this all winter I just couldn't stand watching the ducks shiver. Again I am a first timer all help is welcome.
