Injured Rooster--can we safely butcher him?

My boyfriend and I are fairly new to chickens and raised 8 chicks this year, one of which turned out to be a Welsummer roo. We were hoping due to his breed he would have an ok temperament, and we could keep him...but he started attacking me right around 20 weeks of age a few weeks ago.

Today he attacked my boyfriend who was replacing the water in the coop. He kicked the rooster, the rooster attacked him again, so he kicked harder. The bird went straight backwards through the air and didn't hit a wall or anything, but has had one droopy wing and has been huddled and not ok ever since.

We never intended to have a rooster and I somewhat doubt his injury is fixable. We are not experienced at chicken slaughtering so I was thinking about placing an ad on Craigslist and having someone come take him tomorrow. But I am actually guessing that due to his injuries it is possible he won't be good to eat. We have no idea if he is bleeding internally or not.

I am guessing the best thing we can do is kill him quickly tomorrow if he is still alive in the morning.

Just looking for any advice or wisdom we may not have as new to chickens people. I read through the chapter on butchering meat birds in Storey's Guide to Raising Chickens. It sounds like a big enough task that I think we need to set our sights on a humane death here, and not being able to use him as meat.

He'll be fine to eat. It isn't that hard to process a single bird. You just need extremely sharp knives.
There's lots of good youtube videos on the subject. You fed him all this time, you should get to eat him.

Everyone has their own ethics when it comes to their backyard chickens. Some people see them as a food source some as pets I respect that but ultimately I believe that no matter what your attitude is regarding your chickens that they as all other living things deserve the right to a humane death. If you can't find someone to do it for you my advice is take him to the vet to be euthanized - it might cost a bit (under $100 I'm assuming it wouldn't be that expensive!) but at the end of the day he shouldn't be in pain for longer than necessary. Even if you take him to an animal welfare clinic/organisation they might be willing to adopt him and help him recover (it might just be a broken wing!). I am also new to having chickens and faced a crisis myself recently so I understand what you're going through. But it is your choice - the advice I'm offering is to try and make it humane if you end his life.

First young roosters are a pain in the butt,they are nothing but walking hormones,good news is that they do settle down. I have 6 roosters and when young they were testy,now i can pick up any of my boys whenever i want with no problems,love my boys. Word to the wise,most roosters hate all mechanical devices/tools,so never walk around with them in your hand b/c the boys will attack.

Second never,ever kick any animal hard enough to do damage,now this poor bird is suffering and you cannot just leave him sitting in some corner.

If you are not prepared to deal with his injury then give him to someone who will or humanely put him down.

Thanks to everyone who replied...I posted an ad on Craigslist and a more knowledgeable chicken person showed up and took him away for dinner.
