Kurt flew into a wall

Kurt is okay now but he is not eating very well. He is in a sleeping position but not sleeping. I think he is warming his beak or something. I got an appointment to see a vet in 3 hours today. Kurt is a free bird, roams around the house by himself. He flew into the window once in 2013.
He was pecking at his seeds but can't break them open. So, I peeled a banana for him, he is pecking at it (it's very soft), I mashed some cooked couscous in some water for him. He pecked at it a little.

His beak is a little loose. He needs to orally take medication & have an ointment put on his beak/cere.
He needs to take it easy for the next few days - limit his flying... He needs to rest (he is 10 years old). I asked them if it was possible to have him stay at the hospital so that they can give him the medication (if he does not orally take his meds, they will give him injections). Kurt is staying there for 3 days. It will take 2-4 weeks for his week to fully heal and it may be a little crooked.

I noticed that he was not able to eat yesterday, I gave him some banana peel, and some couscous (very well cooked) with some curry sauce (he loves flavourful food).

When I pick him up, I will get some baby food (fruits, veggies) and make him more couscous.

I wanted the doctors to keep an eye on him for the first few days because he needs to get used to the meds and he needs to rest. If I brought Kurt home, it would have been difficult to give him the meds. He HATES being held. I had to pay a little extra but it is worth it. I will update you once I pick him up in 2 days.

I think the hospital is best for him with his injury, so sorry this happened to him.

Update - called the hospital, my two options are: beak amputation or euthanization.
Beak amputation means he'll be eating baby food. It will be a HUGE change for him. Again, he is 10 years old.
I do not want him to suffer. I would like to hear some thoughts, please. Thank you.

I'm supposed to pick him up tomorrow.

Is that really the only solution for his diagnosis? I'm so sorry to hear this. Have you considered getting another opinion from another avian vet first? It may help to put your mind at ease whichever choice you make.

I would get a second opinion, there have been artificial beaks made for birds that have had a traumatic injury take a look at these A Printed Prosthetic For A Damaged Beak – Pet Birds by Lafeber Co.

Kurt's beak was tearing from the root. He was not going to have the top beak at all. I didn't want him to get any infections, dry mouth... He would've had to be fed by a syringe.

He flew over the Rainbow Bridge around 1300 today 😢

I am so sorry for your loss, fly high sweet Kurt.

I am so sorry for the loss of your sweet boy. He can now fly free without pain or suffering 🧡 Rest in peace, little one.
