Sick or Injured? Chicken falling down.

[Wiskit]

I have a bantom chicken displaying balance issues or weakness. He staggers and falls mostly onto his left side. Any ideas about what's going on? Toxicity, stroke, disease, dehydration? The flock has constant access to clean food and water. They live in North Eastern Nevada. As Im not a native to this area Im not sure if we have any insects or pests that are toxic to eat or if this is a neurologic disease. My kid said it started doing this a week or two ago. He is maybe 2 months old, has not been free ranging but the flock had eaten all the weeds in the new coop. Mostly the few plants of spotted knapweed, mustard plants, and cheat grass. Water here is public and is treated. Food was fresh a few radish tops 2 days ago.
Here is a YouTube video:

Video, & or pictures will help?
An ear infection can cause balance problems, check his ears out?

Absolutely. I tried uploading a video but it was an mp4. This apparently was not an acceptable file type

Upload it to YouTube, & link it back here?
The video upload on this site doesn't work.

Check it's ears first? If it's not an ear infection then might be something like heat stroke, or possibly something neurological.

Just out of curiosity, now that I've just learned that chickens have ears, is there a YouTube on that?

Seriously? An ear infection isn't deadly.
