I'm not on Facebook, would it be OK if you can ask her to talk to me here?

OK, but she always likes to see pictures. Can you post a picture or two of the way that he's standing? I realize that it probably won't show much but a bird standing on one foot, but she's great at picking out small clues that the rest of us miss. If you could post it in a separate thread with a brief description of what happened and how long he's been doing this that will be helpful. Once the pic is up I'll ask her to take a look. Also mention whether he's eating well, if his poops are OK, and whether his behavior seems normal otherwise. Basically as much relevant info as possible.

Here is the photo I took just now before I even saw your post

That's the foot, he also just broke that feather on his wing but he plucked it the second I finished taking the photo

I've asked her to take a look.

It seems like Susanne isn't going to come so I've asked Casey to take a look. Due to Munch and Tsuka's biting habits, she has way too much experience with foot injuries.
