I have two Americana/EE hens that I have been with me about a year now. They have always and with out fail laid identical pail blue eggs. But starting yesterday I have been getting smaller green/Brown (dark brown not tan) eggs. They are the only two in the flock who lay colors eggs. Everyone else lays tan or pail Brown eggs. I started feeding fruit and veg more often as a way to help them stay cool but they usually free range a few days a week? Could.what they eat affect the color of the eggs so profoundly. I know from reading a few other thred that color change isn't unusual but it seems the trend is to lighten in color not darken
