I need to have more faith for this process, we were on day 5 and had both started wondering whether or not the eggs were fertile, *nothing* was showing, even on the white eggs, when we candled. So we decided to confirm for ourselves whether or not they were, and we cracked one.. Beautiful veins and a tiny little baby chicken. Who kicked. I'm done candling. Unless they stink or explode or something like that, I am leaving them alone. Talk about learning the lesson the hard way.
