My girlfriend and I recently started 33 Pekin/Khaki eggs at various recorded times and our X1 generatiom is coming due! We have noticed two eggs rocking a little now and then but it appears as if they take a lot of rest inbetween the bursts throughout the day. One egg is still calm and moving around in the candling, the other a day ago we noticed some tapping sounds and could feel his vibrations. I thought he was trying to break out, i assume this period is him pipping internally. He has since stopped and still twitches around when candled. Today he started forming some blue coloration to the shell around the air pocket and I need to know if this is good or bad. He still moves when candled, but I need to know whether to perform careful surgery or leave him be. Also I assume turning those eggs should stop correct?
