What’s the difference between fertile eggs and free-range eggs? What is a Grade AA egg? The answers lie below.
EGG COLOR
An egg's shell color is primarily determined by the chicken's breed and its genetics. Diet and environmental conditions do not affect the shell color. Pigments are applied during the 20 hours that the egg forms in the hen’s oviduct. A quick way to guess a hen’s egg color is by looking at its earlobes, e.g., white hens with white earlobes typically lay white eggs.
