Broken tips are a regular event with us, especially for the little guys who's beaks are not as robust as say a toucans (LOL). Usually when its the very tip like yours, we just watch to make sure there is no blood and if it is still attached, we clip it (though this will only happen if it is only the tip like yours). In more severe cases where there is severe damage or cracks farther up the beak, we do take those immediately to the vet.
And just a tip for those of you who deal with bloody nails and beaks and whatnot.... a cheap, homemade clotting recipe is flour and cheyene powder. Mix enough together so that the flour turns kind of pink. grab a pinch of that and hold it on the bleed til it stops. Works like a charm.
Blood feathers are a different issue. Do not use a clotter. I'm sure there are topics about this elsewhere pertaining to this issue.
