I have been looking at some of the Arucana and wonder? Can you find the sellers by egg color. I have seen the great color chart but when I see them for sale I do not see mention of the color grade for the eggs? Can you breed for the egg color? If a chick hatches from the bluest of eggs will it lay the bluest of eggs? ho w can you find a seller who's eggs measure high on the charts wether rumpless or not???
