Easter bunnies' laurels threatened. Government experts enable hens to color own eggs. Washington, D.C., April 7. An interesting experiment is in progress at the National Agricultural Center, Beltsville, Maryland, whereby hens color their own eggs over a range of hues from a pearly white through brown to sky-blue. This picture of Charles A. Denton, Junior Chemist, at the nutrition laboratory, shows the method of measuring the yolk index. Eventually we may anticipate a uniformity of eggs in shape and in yolk color as well as a definite amount of proteins contained in each one. 4.7.39
