Cheepers (turkey's name) is doing better all the time. A couple of days ago, it started putting its foot down when it walks, though it has a definite limp and doesn't put weight on it when standing.
Just an update. We had to put our baby turkey down a couple of weeks ago. It was walking around fine but when we moved it to a bigger pen, it started limping again and finally stopped walking altogether. I think it was that his leg couldn't support his increased weight as he grew.
