"altered mental status" hen?

No one can upload videos to BYC, the site is not set up for that type of media. Everyone uses mediums/hosts such as youtube so the video can be embedded by linking from the host site.
DO YOU HAVE A GOOGLE ACCOUNT? If so, you have a youtube account w/o signing up. Google owns youtube. I use my Google user name and password to use my youtube stuff.
I can't view the video you posted in that link.
From the photographs, The bird looks healthy. A deep dark comb. I'm guessing egg bound or borderline broody still without witnessing the behavior you are describing. So I'm sorry I can't be of assistance.
@lazy gardener might have an opinion.

I can view it on my computer, maybe try that
