It's a scheme to C compiler (with an interpreter, of course) that implements Cheney-on-the-MTA compilation (so continuations are almost free), a very nice macro system (although with some unfortunate performance implications), and has a relatively large library repository (for a scheme), as well as an stdlib that emphasizes practicality over purity (it even includes a regex library in the default install) while still keeping the simplicity that makes me love Scheme: I can keep the whole language in my head. Plus, if it doesn't have the library you need, writing C bindings is a piece of cake (because it compiles to C, anyways).
At the risk of making it known that the joke went over my head, can you link me to the Awful?
The only "chicken" programming language of which I'm aware is this one: http://torso.me/chicken
