Baby chick with derpy leg

[Another leaf]

I recently got a few more chicks and one of them has a leg that they can't use

Basically it's fused at what I'd call the knee, it's essentially useless, poor bugger can't use it at all and hops around on the other leg.

I want to give him the best chance but I also don't want him to suffer. When he gets bigger it's going to be hard for him to scratch and I don't want to put him through that if it's pointless

So my question is what do I do with him really. Can a 1 legged chicken get to a proper culling size happily or should I just let him go?

Can you take a clear picture of the chick standing? Or a clear video and upload it to YouTube?

The leg is basically stuck in this position. He manages to get around really and I don't think it's hurting him. I thought it was curly toe at first, had a little shoe on him but that's obviously not the case now
