When hatching eggs laid by Rhode Island Red hens fed a diet deficient in vitamin B12 were injected with crystalline vitamin B12, the hatchability was improved. Among the chicks hatched from vitamin B12 injected eggs, the growth rate was greater, the mortality lower and the feathering better than among chicks hatched from H2O-injected and non-injected eggs.
