chicken with sudden strange symptoms - please help

[claudiabruckert]

All of a sudden,one of the hens started to tilt her neck backwards, spread her wings, and move backwards. That lasts for a minute. Then she seems to be fine until the next episode.
She has a good appetite Does anyone know these symptoms and what disease might be causing them?
The hens are about two years old, have always been together, and get to roam.

It sounds neurological such as with a seizure or possible wry neck (torticolis.) Vitamins (thiamine, E, and selenium) should be given. There are some examples below, and a few links to read:

Our chicken's condition hasn't improved. We've been giving her bacopa monnieri, vitamins B1,2,6,12, and selenium. When she is being carried, she doesn't have symptoms. When we slightly push the head forward during one of these fits, the symptoms stop. When she drinks, holding up her head to swallow starts a new fit.
Do you have any other suggestions?

Have you been using vitamin E? Vitamin B1, E, and selenium are the vitamins to use. In some cases people try prednisone. If so, then I don't have other suggestions. Many cases of wry neck or neurological symptoms can't always be cured. Many people treat it for weeks, some see improvement, while some don't. You can read some threads here incase someone else has had a similar case:

She died two weeks ago. Now I think that she might have gotten pecked on the head by the rooster. Her symptoms started so suddenly.
