I recently found this naked neck chick being unable to walk.
What is the reason why it became like this?

Try searching "slipped tendon" and see if it matches what you are seeing.

One thing that I can blame for this is maybe the newspaper.

Honestly not sure, but giving the vitamin supplements could help, pending further advice.
