Split beak

[ForFlocksSake]

This hen always has a split like this to some degree. Any idea what causes this? She’s perfectly healthy otherwise and none of my other girls have this issue. She’s lowest in the pecking order and definitely gets picked on, but not sure if that would be a cause for her beak to look this way.

Could just be from an old injury. I would think it is similar to when a finger nail splits, it keeps growing split unless you can cut it back to where it isn't split.

If you can keep it nicely trimmed perhaps it will resolve?
