Slipped tendon - rooster

[Lulu-vt]

We had a little guy born to our broody. She laid on 12 eggs and he was the only one to be born. When he was born, his leg went behind him. I knew something was wrong. We tried splinting but it didn’t help. We thought maybe he would get stronger and it would be ok.
Well, his leg is not ok.
I think he has a slipped tendon. His leg seems to be on the outside of his joint or just wrong. He can hardly put weight on the leg. It has gotten worse as he gotten bigger. He mostly stays in the coop hiding or just being submissive. He does eat and gets out to drink water. He has grown nicely. He is 4 months old now.
I don’t know what to do. He seems uncomfortable. I can’t cull a chicken. I don’t know how and I would do it wrong. Can I take him to the vet? Is that insane? I spoke to her in passing at the store a month ago and she said that would require surgery. Surgery for a chicken?!! Ridiculous, right?
I know he’s just a chicken but he deserves to have right done by him. What would you do?

I was trying to add a video. But maybe I can’t do that here.

Slipped tendons and leg bone deformities are common in all poultry. The common leg bone deformities, varus or valgus and twisted tibia, can affect one or both legs, and get worse as they grow. Can you post pictures of him from the front and back to see what his legs look like? You are fortunate that he is able to get around well enough to eat and drink. Some may live a long life in a smaller area as long as they can eat and drink. Here are some articles to read:

I’ll give that a read. Thanks. Here are some photos. It’s his right leg that is affected.
