If you think it looks like a neurological tremor, I'd give her vitamin E. It's not a 'cure' but vitamin E deficiencies are not that uncommon. Vitamin E helps heal neurological issues.
You can buy 400 IU vitamin E gel/oil capsules for humans. Slit the end of one and give the chick a drop. Keep in a dark place for the next day. Treat daily until you see improvement.
Can you tell us more about her general circumstances:
What is she eating exactly?
Is she receiving any supplements?
Are there birds of other flocks/ages near this clutch?
Were the birds vaccinated for Mareks? i.e. are they from a hatchery?
Is this your only or first flock on the premises (including past owners)?
Have you checked her thoroughly for mites/parasites?
Is everything else (including her weight, rate of growth, feathering) completely normal if not above par? Or is she slightly unthrifty?
Has their water been getting into their bedding or feed at all? ANy rain? Did she eat any wetted feed? Any other foodstuff that's wet left out in this heat?
In the mean time, here's an article that Glenda Heywood found that I'd like to share with you:

Nervous conditions
in poultry
WHAT ARE NERVOUS CONDITIONS?
Nervous signs occur when the brain, spinal cord or specific nerves are affected. Different organisms or poor feed can cause nervous signs in chickens. The most frequent nervous signs seen, are:
Chickens lying down because they are unable to stand.
Walking with difficulty as if in pain.
Necks twisted or turned to the side.
Staring into the air and not knowing where they are.
Shivering.
WHAT CAUSES THESE CONDITIONS?

Good clean management is advised to all chicken owners
The following diseases cause nervous conditions in poultry. They are listed in order of how frequently they occur.
Newcastle disease
Epidemic tremor
Marek's disease (range paralysis)
Botulism
Poor feed can also cause nervous signs. Usually this is because of a lack of vitamin B2 or vitamin E. Poison can also cause nervous signs. There are many pesticides that should not be used on or near poultry.
FEED AS A CAUSE OF NERVOUS CONDITIONS
A lack of vitamin E causes crazy chick disease. This occurs in chickens 2 to 3 weeks of age. Typical signs are muscular weakness: frequent falling, head and neck pulled towards the back, paralysis and eventual death because of starvation.
A lack of vitamin B2 (riboflavin) causes curled toe paralysis. This occurs in 10 to 14 day old chicks. A lack of this vitamin affects the nerves of the wings and legs. Typical signs are reduced growth rate: legs are stretched out, curling-in of toes, drooping head, wings and tail feathers.
Birds are still alert. The paralysis leads to death as a result of starvation. In early cases giving vitamin B2 in water leads to a rapid recovery.
In order to prevent these conditions you must make sure that you are feeding your poultry correctly (properly formulated chicken food).

Added by N Ross: Riboflavin is available in a bioavailable form via dairy products. Plain yogurt would not only encourage her gut bacteria to produce more B vitamins, it also provides bacteria that produce enzymes that help the bird to more fully digest and absorb other nutrients. It'll help her thrive. At her age, one teaspoon would work.
