Does anyone know of any build along threads for making a wool hen (insulated enclosure used for chicks to warm themselves using their own body heat, used in lieu of, or in supplement to artificial heat sources), or multiple ways of making them? I have checked a couple threads and people have described how they made theirs, but a detailed build along with pictures would be great. I am thinking of making one to try with my next hatch, but would like to see as many ways as possible for the concept to be carried out.
