Chicken Egg Colors
Why are eggs different colors? Some are white and some
are brown. Also are these the only two colors eggs come in?
Egg colors are determined by genetics. Brown chicken eggs is the original
color, however, some hens were found to produce lighter eggs, and with time
and breeding selection, white eggs became a reality. During the 50's white
bread (bleached flour) and white eggs, and "white" became the symbol for
and was accepted as the determination of "purity". It was not until the
late 70's, that brown eggs were re-introduced into the market [widespread].
As far as the quality of the egg, it does not seem to be any difference.
With the new technology, science probably could make the eggs come out any
color!! But, why?
