Hi! These are my first chickens and they are all about 7 months old. I have 1 easter egger and I've noticed her eggs vary in color from day to day. Some are more green, some are almost olive colored and some are downright blue. I was under the impression that a chickens egg will be a certain color and never change but apparently I'm wrong. Since I only have 1 easter egger I know all of these are hers. Can someone help me out here and explain how it works? Thanks!
