My eggs were due to hatch the 1st. One hatched a day early and another on the 1st. My problem is that one of the first to pip still has not fully hatched. I can see that it has cracked the shell completely around. I have about 4 that are still pipping this morning before I left for work but since it's been 4 days what should I do? I've read to leave them alone which I have done but then I read to wait until day 25, which was yesterday. Any help would be greatly appreciated.
