Buck with Arrow in Neck

I have a buck with an arrow in it's neck I want to remove or cut short. The buck knows me and has had the arrow in it's neck for about a week. A neighbor posted it on Facebook 5 days ago and now he's at my house. He's camped under my deck. It's not hunting season and probably got shot by some moron. I suspect a teenage moron. I can't get Fish and Wildlife or any agency in California to help. Does anyone know of any oral tranquilizer that would work?

Thank you. I found the pellets and that would calm him down. He's a large buck and I need to knock him out. Calming him I might still get the horns. I can get close enough to pet a doe but the bucks won't let me get within 15 feet.

I have some Percocet from my recent blood clot but don't know how that would effect him so I'm reluctant to try that.

Yes, I called a local big animal traveling vet and she said the same thing...that people drugs affect animals differently. She was prohibited from working on wildlife and could not help me. I mentioned the percocet to try and get her to offer some information one way or other but she said she had no experience with deer. I was willing to pay someone to help the buck after getting the hand from California government resources. No one in California will help me. I am so unimpressed and so frustrated. I don't know where else to try and find help. My property is zoned agricultural. If you guys farm deer don't you have traveling vets that work on them? What makes your deer farm animals and not wildlife?

Yes
