As for not moving it, yes, it will work. We raised some layers in it over the winter, until a weasel climbed it and pulled back some of the tarp to get in killing the hens. That was a major reason we now surround it with electro-netting. For winter insulation I lined the interior with mulch hay and then broke up a bale at a time for flooring to allow the decomposition of the waste and hay to provide more heat.
