This is what I read. But it seems like there is another article I read. I will keep looking. Something about genes, rather than nutrition.
deficiencies of the following may cause:
*Vitamin B2 (clubbed down, curled toe, micromelia, degeneration of the myelin sheath of peripheral nerves, degeneration of embryonic Wolffan bodies)
*Biotin (chondrodystrophy, syndactyly, characteristic skeletal deformities, ataxia, and chondrodystrophy in newly hatched chicks)
*Folic Acid (chicks may be of normal appearance but die soon after pipping; in severe depletion chondrodystrophy, syndacryly, and parrot beak)
*Vitamin B12 (malposition, myoatrophy, chondrodystrophy, oedema, hemorrhage)
*Manganese (chondrodystrophy, parrot beak, globular head, cervicothoracic oedema, retarded down feather and body growth, micromelia and ataxia in newly hatched chicks) - bone formation defects are probably associated with abnormal mucopolysaccharide in the organic matrix of bone. Vitamin B12 and manganese deficiencies may be associated with extreme reduction in hatchability.
Definitions for those who may not know:
chondrodystrophy: A disturbance that affects the development of the cartilage of the long bones and that especially involves the region of the epiphysial plates, resulting in arrested growth of the long bones.
myoatrophy: atrophy or wasting away of the muscles.
syndactyly: A condition in which two or more of the toes are joined (fused) together.
oedema: The presence of an excessive amount of fluid in or around cells, tissues or serous (resembling, producing, or containing serum) cavities of the body.
micromelia: abnormally small and imperfectly developed extremities.
ataxia: shaky and unsteady movements or loss of the ability to coordinate muscular movement.
