Injured duck, slipped tendon?

[Kiki to Nana]

Hey! I am looking to help a person on Facebook who has pretty much exhausted all options for her little friend.

Here is a link to the video for the poor guy.

Hopefully it plays.
What I know so far is she has addressed the feed and adding brewers yeast as well. Going to begin swimming time to help exercise the leg.

Does anyone know what could possibly be wrong? Some of these people on Facebook are too quick to judge and are clueless.

Can you get more pictures of his leg?

 

[Kiki to Nana]

I'll try.

Are you able to watch the video from Facebook?

I can't see the video since I am not signed up for face book.

Well shoot, let me see what I can do.

That leg looks twisted or broken. I'd reccomend Taping the leg with a firm stick or if you time, to avoid the potential threat of paralysis I'd build a walker sling for the little guy

Something Like this(Although you should cut two leg holes)
Here's a useful link to the video that helped me repair my duckling's broken leg:

It is for chickens, but it also works for ducks.
Hope I helped
