Good to hear the chick has hatched ok. If you have another piping at the wrong end of the egg this would point me towards something like the eggs have been incubated the wrong way up. Did you have them in a turner with the fat end up during incubation? If they were incubated with the pointy end up they could have formed in the wrong position. Also how the eggs were stored prior to incubation can affect how they form too.
Good luck with the rest of them, keep us posted.
