Where can I download tutorial Space Chicken source code?

As far as I can tell there is no source code for this particular tutorial, because the tutorial is about using ‘“Ready” a free application built on Unity’. So, for this tutorial you just download “Ready” by following the link in the tutorial’s page, not source code.
