I'm not sure what to do, I need some advice. I have one egg that started to pip yesterday afternoon. I've been checking on it all last night. Early in the morning around 3am still only a pip. This morning minutes ago I checked it and it's zipped 3/4 around the egg. The question is...it hasn't cut through the membrane. Should the membrane have been broken by the chick, or do they just break the shell, then cut the membrane after? It appears the membrane is still sealed. It's a bloody white color. Is this normal? Should I help and break the membrane?
