It depends.
Battery birds were often debeaked to prevent injury in cages.so she might be fine.
It depends on how they damaged happened and weather it was just the beak or was any damage done to the skull /orbits /eyes etc.
Is there any infection? might need tylan. May also need soft / crumb food if she has trouble eating.
I cant really see the damage clearly in the picture, I have repaired a split beak with superglue before now ( in the dark with great care).
