Good news is the beak will grow back if broken at the tip,but it is very painful,similar to having your nail ripped off halfway down nail bed. Has the bleeding stopped? He probably will not eat for a day or so due to pain. Make sure he is drinking,might help to give him water that is at room temp or a little warmer. Give him soft foods,try scrambled egg,oatmeal,bananas,cat food,etc. Try adding warm water to his feed so it resembles oatmeal,this may be easier for him to eat. I would bring him inside for awhile just to monitor him and see if he is able to eat.
That is a good chunk broken off,hard to say it should grow back,but will take some time. To clean any debris off,you can use a sterile saline solution(contact lens solution,preservative free)main concern right now is he able to eat,as this is extremely painful. If he cannot eat or will not b/c of pain,you might need to tube feed him. Try the soft foods,you can also give baby food warm it up a bit(do you know what an exposed nerve feels like in a tooth and how anything cold is extremely painful,this is the reason for warming up food)this is the pain he may be experiencing.
Explain wired,did you take him to a vet and they wired it in place?
