Im not sure which one you are asking about. The fully developed egg or the other 4 that didn't even make it past 10 days. The fully developed chick i did pip on day 24, I was so excited after the first 6 made it!! Then I decided after about 3 hours that there should be some sort of movement, chirping, something.....yet there was nothing, so I began "helping" my chick get out, then I got scared and put my chick back in the incubator with the sack still fully wrapped around it, an hour or two later, no pipping, no movement and then I took the egg out again and decided that I needed to completely remove the chick from the shell. At that point it was too late, it had already been suffocated.The other 4 didn't make it past 10 days. one egg didn't make it past day 3-4, 2 eggs must have gotten a virus, and died during incubation process. One however wasn't even fertilized. It seems really weird because I candled each at day 7 and found the veins and the heart beat, so maybe it was just a trick of lighting or my hopes, but it was a dud.
that sounds to me like the chick died before you started helping. If the shell is opened where the air sac is the chick can still pip through the membrane on their own. There used to be air there before. If there was no movement after opening the one end for an hour then the baby wasnt alive to begin with. It wouldnt have suffocated because of your help. By day 24 it should have already internally pipped. Especially with the yolk being fully absorbed, they finish that after they internally pip over many hours 8 - 12
