This looks exactly like what the "b" vitamin deficiency causes. If that's the case:
-Quick approach (but not natural...synthetic vitamins): Get some Poly-vi-Sol liquid children's vitamins NO ADDED IRON. Put in waterer, but also put some in the beak a few times a day.
-Cut liver from a clean healthy source (grass fed) into tiny pieces or grind it in the blender. Let her eat.
-Brewers yeast (Lewis Labs) to eat.

Riboflavin Deficiency: In advanced stages of deficiency, the chicks lie prostrate with their legs extended, sometimes in opposite directions
In addition, see other vitamin deficiencies that can lead to leg issues including Vitamin E and D3 in the Merk Manual: http://www.merckvetmanual.com/mvm/poultry/nutrition_and_management_poultry/vitamin_deficiencies_in_poultry.html
Here is a quote from a former post in the thread that may also be helpful:
it is often a sign of riboflavin or thiamin deficiency. If you are feeding medicated feed, the med has the effect of blocking riboflavin from being utilized by the body. Even if you aren't feeding med. feed, the need for riboflavin from a "meat" source (bugs, mice, etc...items that they can catch on their own if they were with a broody on range) are usually lacking.
IF it's a riboflavin deficiency, you can add the "b" vitamins "naturally" by purchasing some clean beef liver and chop it into tiny pieces and feed RAW. Sometimes you will see improvement almost overnight but you have to catch it early!
Even if it isn't riboflavin deficiency, feeding chopped RAW liver, ground meat, etc., it a good way to ensure that they get "b" vitamins from a natural source. Vegetable sources of the "b" vitamins are not as bio-available and much of it is lost. One way to increase the absorption of the b vitamins from raw grains is to soak at least overnight to begin to break down the phytates that inhibit b vitamin absorption. Fermenting the "grain source" feed is even better at breaking down the pytates.
There is a lot of info out there but here's one quote:
A decreased rate of growth and lower feed efficiency are common signs of riboflavin deficiency in all species affected. Typical clinical signs often involve the eye, skin and nervous system. The most critical requirements for riboflavin are those exhibited by the young chick and the breeder hen. The characteristic sign of riboflavin deficiency in the chick is "curled-toe" paralysis. It does not develop, however, in a total riboflavin-free diet or when the deficiency is very marked, because the chicks die before it appears. Chicks are first noted to be walking on their hocks with their toes curled inward (Illus. 1 and 2). Deficient chicks do not move about, except when forced to do so, and their toes are curled inward both when walking and when resting on their hocks (Scott et al., 1982). Legs become paralyzed, but the birds may otherwise appear normal. Approximately 10% incidence of curled-toe paralysis was observed among birds fed a diet with no added riboflavin (1.5 mg per kg or 0.68 mg per lb) (Bootwalla and Harms, 1990).
"Polyneuritis in birds represents the later stages of a thiamine deficiency, probably caused by buildup of the intermediates of carbohydrate metabolism. In the initial stages of deficiency, lethargy and head tremors may be noted. A marked decrease in appetite is also seen in birds fed a thiamine-deficient diet. Poultry are also susceptible to neuromuscular problems, resulting in impaired digestion, general weakness, star-gazing, and frequent convulsions.
"Polyneuritis may be seen in mature birds ~3 wk after they are fed a thiamine-deficient diet. As the deficiency progresses to the legs, wings, and neck, birds may sit on flexed legs and draw back their heads in a star-gazing position. Retraction of the head is due to paralysis of the anterior neck muscles. Soon after this stage, chickens lose the ability to stand or sit upright and topple to the floor, where they may lie with heads still retracted. Thiamine deficiency may also lead to a decrease in body temperature and respiratory rate. Testicular degeneration may be noted, and the heart may show slight atrophy. Birds consuming a thiamine-deficient diet soon show severe anorexia. They lose all interest in feed and will not resume eating unless given thiamine. If a severe deficiency has developed, thiamine must be force-fed or injected to induce eating."
When I first heard about various "B" vitamins having an effect on leg issues w/chickens was a few years ago in one of Joel Salatin's books. Here is some info that is very interesting on riboflavin in young chicks in particular. I think if you click on the images they will come up large enough to read.

Someone had remarked earlier how they wondered how the birds could be fine one day and not able to walk the next. In another part of JS book, he mentioned that was what happened. One day they were in that condition. After feeding the liver, they recovered quite quickly as well.
