How is she? Is she by chance straining? I can’t get the video to play, but I once had a neighbor who had a hen who would close her eyes and open her mouth… she asked me to look at it… she thought it was respiratory, but She was actually trying to lay an egg and was straining when she did this. She would also lift her tail, but barely perceptible, so the movement was initially missed. 
so sorry. I hope she recovers.
