Table 5.13. NRC (1994) estimated vitamin and trace mineral requirements of growing and laying chickens, amount/kg diet (90% moisture basis).

It is common for egg-laying strains (e.g. Indian Runner) to be fed diets similar to those for brown-egg strains of chickens. 

Ducks (Anas spp.) had reduced survival when fed diets containing 2500.0-3000.0 mg Zn/kg ration or when force-fed zinc metal shot equivalent to 742.0 mg Zn/kg BW. Domestic chickens (Gallus sp.) were more resistant 8000.0 mg Zn/kg ration was fatal to chicks, although higher doses were routinely fed to laying hens to induce molting 2000.0-3000.0 mg Zn/kg ration inhibited chick growth 178.0 mg Zn/kg feed caused... 

Besides their color, the only difference is the color of the chicken that laid it White-feathered chickens lay white eggs brown-feathered chickens lay brown e s. That s it The inside of the eggs are identical in every way, assuming the chickens you re comparing were on identical diets.
