wheezing no other symptoms

6 month old hen, was seemingly fine yesterday. I went into the coop about an hour ago (still plenty of daylight) I heard a soft and strange cluck/chirp, found her on the floor. I don't know if she left the coop this morning. No wounds or injuries found. We're in Montana and have had a couple cold wet days. I'm at a loss...and can’t seem to add a video to the post.

To add a video, its easiest to upload it to youtube and then post the link here.

Is she lethargic at all? Are there any bubbles in her eyes? Does she have a runny nose? Any swelling of the face?
