Set babel scheme to chicken?

Set babel scheme to chicken?

I have a few schemes installed on my computer (MIT, guile, chicken), but
when I run such code as this

#+BEGIN_SRC scheme :session one
(define (myadd x y)
   (+ x y))
#+END_SRC

it works -- beautifully with multiple REPLs (as you name them in the
:session) -- but it always grabs the guile. I'd like it to use chicken
instead -- or maybe later MIT. I've got latest geiser installed as well
that should handle chicken. How can I use chicken inside of orgmode scheme
code blocks? Wild guess, guile is first on some list, i.e., path? babel
customize didn't seem to have an entry for which flavor.

Looking at the code, there is a :scheme header argument that can
indicate what scheme implementation should be used.  Otherwise, it
appears to use geiser-impl--implementation, which a comment says is
defined in geiser-impl.el.  There is also geiser-default-implementation
and geiser-active-implementations from that same source.

Not sure what the :scheme header argument might be or how to change it.
However, changing the geiser-impl--implementation (changed order to make
sure) and geiser-default-implementation seemed to do the trick. My bad
overlooking this.

Thanks,
LB

I think this might work, but don't have a scheme to check it out.

#+BEGIN_SRC scheme :session one :scheme chicken
  (define (myadd x y)
    (+ x y))
#+END_SRC
