I took pics of the injured leg. It is his left hock joint. I see nothing except maybe the tendon is out.
Bad leg (left, he is upside down too)
Top of bad leg
Good leg
Both legs
I was going to splint the hock joint like this -
I tried to find and re-place tendon and failed because its only easy if you already know whats actually wrong and what you are already doing. Gonna seperate him. Mirror no longer consoles him though. I feel it causes even greater stress but he needs to heal. Any ideas based on pics??
Gosh, it's hard to tell from the pictures. It doesn't really look like splayed leg but you may try splinting its legs together with a band aid or vet wrap. Here are a couple links on leg problems in poultry and how to splint:
(also, if he is really lonely, you might try putting only 1 other keet with him once in a while to keep him company).
