Chick nose missing! Help

[Porterfive]

We have just got 3 six week old (we think) Buff Brahma chicks. They are all healthy except one has her nose missing. Her beak seems fine but in between her beak and comb area, is just a big dip, her nostrils are visible in the hole and seems clear. She has no discharge and seems to be breathing normally. I am sorry this isn't a very good discription but the best I can do.
Does anyone know what this problem might be or if there is anything we need to do?
Thank you in advance for any advice.
Jenny,

Interesting...As long as she's doing fine, then she should have a long and happy life.

Other chicks have pecked it's nose, not common in chickens but common in gamebirds, it will be fine

Well Pine Grove, interesting you should say that. The chicks were in a cage with quail chicks when I got them. They probably did it to her.
Thanks for your input.
