Wondering what causes green yolks? I have 2 Easter eggers and some RIR's that are about 1 year old. One of the Easter Eggers started laying about 2 months ago (4 months after the others started). The color of her eggs are dark green on the outside, smaller than the other eggs and what is really odd is the yolks are dark green and the whites are not clear but dark color. So far I have been tossing them since they don't look safe to eat. Any ideas what causes this. All the chicks are eating the same Egg Layer food.
