Hi all I am thinking of hatching some eggs in the spring. I am looking at incubators and especially used ones. Can the Styrofoam ones be cleaned and sanitized? I would want to use it over and over when I add new hens to the flock, and I would like to get some fun, rare-breed eggs so I would like to do everything I reasonably can to ensure a high hatch rate and healthy chicks. Anyone have any suggestions or advice?
