We are building a insulated addition onto our daughters coop for her bantams. Just wondering what thoughts are on the flat panel heaters for coop use. We live in Wisconsin and it gets very COLD and she wants to keep nice combs and happy birds! The coop is being fully insulated and ventilated for her 15 bantams she is showing. I like the idea od the flat panel heaters ebing fullu enclosed and much less fire risk. Has anybody bought the ones from ebay, don't know what the difference is from the panel heaters on henspa or shopthe coop?
