I just think its misleading to a newbie. They may live in dry climates and make the mistake of thinking eggs need no humidy when hatching and loose their precious chicks that they have been looking forward to arriving. Slide your hand under a hen that is setting and u will feel moisture. Instead of preaching "dry hatching" the individuals could simply remind others that they are lucky enough to have a humid environment in which they do not need to add extra water. Again i stress to the newbies monitor your humidity do not just assume that there is some magical "dry hatching method"
