Lala...it sure sounds like the b vitamin deficiency issues and symptoms. (See quote from Merk manual below)

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."
Since it sounds pretty bad at this point and assuming you want to try to save them, I'd get some of the Poly-Vi-Sol (NO ADDED IRON). You can get it from almost any place that sells baby items (
walmart, etc.) Be sure not to get the one with additional iron.
I know it's not a natural cure but they may be advanced enough to try synthetic as a desperate attempt.
Keep feeding the liver too...but this sounds quite advanced if that's what it really is.

If you want to try to bring these kiddos back to health, this is
what I'd try (may sound drastic but you can decide...this is just what I'd do):
-
REMOVE SOY from the diet. It can bind the b-vitamines, making the indigestible to the bird.
-
Grains that have not been fermented or sprouted also inhibit b-vitamin absorption and can act as an anti-nutrient that can cause b-vitamin and mineral deficiencies. Since they are not thriving, I'd be sure any grain-based feed I give at this point is either sprouted or fermented which removes some of the anti-nutrients and makes the vitamins and minerals useable.
- I'd feed as much meat as possible...some ground meat 2-3 times/day until you see a great deal of improvement. Some of this would the the chopped liver...at least a little each day. You can reduce the amount of meat if you want after they get stabilized.
You might be wondering why all your chicks don't seem to have the problem. It seems that there are some breeds (including Cornish X and SFH) that seem to have either a higher need for these vitamins and/or have not been able to adjust well to grain/legume based diets due to their genetics. I've read of a person who had 100 Cornish X that came down with the symptoms, recognized them, fed them liver right away, and they recovered and grew. This same guy had been raising other groups of cornish that had no problems.
Was it a deficiency in the specific feed he was using at that time? Anything is possible as crops vary from place to place.
The main thing is that getting that liver to them right away - before they were too far gone - brought them back to health.
