From what he/she has told us, he is not suffering. You say killing him is putting his feelings above yours, but how can you say that? The entire creation of that animal has been born from people caring more about having fried chicken than an animal being able to walk. People will purposely get these for flesh and then say it is only fair to kill them before they are in pain, but the reason these birds keep being made is because people keep buying them! They are the reason Cornish x are in pain. In the OP's case, she accidentally got them. If he is a friend and a pet that she cares about, she would probably kill him when he was obviously does not want to live anymore and cannot get around, but she may not. To kill him as a preventative measure like you say he/she should is totally putting your feelings first - your feelings that chickens are inferior animals and livestock. You would not kill your grandmother when she got to be 60 because she could have a painful death later on. But I guess he is just a chicken. You would kill him because YOU thought he needed to be put out of his misery, and that idea in itself is putting your feelings first. It really is not your choice to make.
To the OP: If he does not want to live anymore, you will have to make the choice to end his life or not. In the end, the choice should not be about what anyone but the chicken wants, or anything that anyone else tries to tell you about them. This is an animal that is surrounded by biased misinformation.
