I've combed through the archives and no one seems to really address this idea - sorry if someone has seen it before. anyway: what I want to know is - what's the best/cheapest way to heat the chickens' water come winter? and will this be draft free? My details: I live in northern WV. chickens are 2 red stars living in a Catawba-like tractor design with a 6x4' footprint. currently there is no top-level floor, but i can insert panels in to make it solid. My idea: was to use a heating cable to wrap around the mason-jar waterer to keep it from freezing. note, the waterer is suspended from the frame to allow easy movement of the tractor. I realized that heat cable can be had in long lengths, so I thought, hey why not snake it around the upper level of the tractor to keep it warm enough up there and maybe keep eggs from freezing? Is this worthwhile? should i just use a heat lamp pointed at the waterer or...? Also, i've read different reports on how draft free they need to be. will the paneled floor be necessary, or will it cause too high a build-up of moisture and ammonia? I *was* planning on lining the floor with a couple inches of straw... so many questions! i know its tough to predict, but maybe folks could weigh in with their thoughts. thanks!
