Crowing
In that case, I think it's a random congenital defect that Easter eggers are prone to, like cross beak. I have been curious if this chick and the others were related to stock from a particular hatchery. Sounds like it's just random. And very rare. Only four posts about this that I can find.No hatchery, came from my own flock
Do you know which parents she came from?
Do you plan to continue breeding olive eggers? I wouldn't stop especially if you're raising for selling eggs, but probably would put some test breeding into action.
If more chicks with this issue come up in future hatches, I'd try changing roosters for one breeding.
If the issue is still there, start keeping track of who is the mother of each egg is.
If you have a mother that throws cross beak or parrot beak type chicks you can retire her to an egg layer flock.
