(URGENT) (VIDEO) Hen suddenly keeps turning neck back falling backwards!

My chicken has suddenly began turning her neck backwards and falling, as shown in the video.

A week ago, I found her on her back and thought she was dying, and she has taken a long time to recover. I'm thinking this movement could have caused it.

What is happening? Why did it happen one night a week ago and now suddenly again?

It's a vitamin deficiency called wry neck.
Give her one 400 i.u vitamin E capsule and about 1/3 a B complex tablet every day for a week or two. you get these from the vitamin section at a drug or grocery store
Just pull down on her wattle and pop them in her mouth.
What's her diet?

How old is she? I'd switch feed types if possible, it a little low in a few areas.
