If she is eating and drinking without any problems then it's probably just fine. Beaks are a lot like our finger nails and will eventually grow back out. That is why you see chickens/turkeys rubbing their beaks against objects to sharpen them and wear them down (think of how a cat keeps their claws in check by running them along trees and heaven forbid furniture).
I had a turkey chip the tip of her beak on something and it eventually grew back out. Fortunately is was fairly minor and did not cause any eating or drinking problems.
