ointment-for-chicken-beak

As you know my chicken got attacked yesterday,  it looks like it was not her tongue that got bitten but her top beak is damaged, it is still attached and all but im think it either cracked or a layer or two came off her beak.  The blood has dried up on her beak, but idk what i should do to clean her beak off, any ideas?  and what can i put on her beak for it not to get worse?
