He was very active when I go him home... as soon as I got the lid of the shoe box that I took him to the vet in he made a break for it (which is a little out of character).
This morning he was a little slower - but I recon he would be in some pain today. (the Vet gave me some pain killers for him - ever tried to give 0.05ml of fluid to a beardie)
He is very used to moving without his legs as he has been in a cast now for about 3 months so I think if anything he will be moving better now that he does not have to drag his dead leg behind him. Give him a week and I bet he will be back to his old self.
