I don't know if all of you guys have heard of the Silver Gene in White Plymouth Rocks but it is a means that they have a silver base which makes them stay bright white even when exposed to the sun or if they are eating lots of corn. Some people call them "stay whites".
Here is a picture of one of our White Rock chicks where you can see the Silver Gene expressed heavily.
