One of the things that has been noticed by some who are breeding the ones with multicolored eggs is that some of them are laying pink eggs. Not white with a light brown coating that is making them peachy but pink shelled. It has been the common thought that the pink eggs in Easter Eggers was caused by a light coating of brown pigment. But several of the breeders here have pink shell on the inside. I have an Olive Egger girl that lays a pink egg with a brown coating. If you peel the inside skin off of the shell after you break it open you can see the pink shell. If you remove the brown coating with vinegar on the outside you can see the pink shell. The shell itself is pink. I believe this to be another gene just like the blue shell gene. I think it may have come with the South American birds that were crossed with other North American breeds. Don't have enough data to guess whether it is dominant or recessive to either the white or blue gene. But the egg shell itself is pink. The odds are that whatever gene causes it is either occupies the same position as the white and blue gene or is very close to it in proximity.
I have been meaning to take the shell to the paint store and get them to scan it for its hexidecimal color (a four digit number that describes how much red, yellow, blue and black are in it). I love the color and want some paint made up to match it and the blue inside of my olive eggs as well as the olive color outside. The beauty of doing this is you have a precise description of the color. Any printer can reproduce the color exactly from the four digit code.
