Pullet shaking and struggles to walk. Video link.

About 2 weeks ago this 7 week old pullet started to develop a constant and severe shake. She is unable to stand properly and walks around with a thumpy gait. She is with 20 odd other birds her age. Her legs don't appear to be broken and she's eating and drinking regularly. Any thoughts?

Here is a link to a YouTube video showing her shaking.
