I was on vacation when two of my hens started brooding. I candled on July 12th and the eggs seemed to be in different stages (my first experience, so can't be sure). I have hens, all different breeds so I know whose eggs are in the 2 nests, some of everyones. On July 15th, one egg was pushed away from the nest with a crack. It was cold, I candled it, and no activity, the attached picture shows the stage of that egg. Because the eggs may have been laid or added after the hens started sitting should I be doing anything special. Can they be at different stages? I have not moved the eggs since the first candling but have looked at them by lifting my hens up. I also don't know what to guess on a hatch date. Any help would be greatly appreciated.
