Top beak broken off at tip. Disease? Just got them last night.

I also put a driveway stone in the pen, my birds always rub their beak on it to sharpen it.
some please correct me but I think beaks are similar to toe nails and continue to grow over time and like toe nails are trimmed by normal chicken behaviour like digging and foragin.

Basssnake - I'm with you, I do not believe there is a breed that has a naturally occurring 'trimmed' beak. Imagine the dollars and time a battery farm could save breeding that anomaly into their caged birds? My three Hylines came with awful trimmed beaks - it did not impair their ability to gobble feed. Last time I looked their beaks appeared to be more natural looking. I will have to check them out tomorrow and see if I am wrong..I have never heard of a 'black rambler' either, so will stand corrected if black ramblers with naturally occurring trimmed beaks actually exist.

So there isn't any diseases or parasite such as mites, etc. That can cause this??

I don’t know, try looking it up, but I don’t think so.
