When we ordered Easter Eggers from a hatchery 3 or so years ago, one was a light yellow with almost a fluourescent green tinge to it. She was not the golden yellow most chicks that grow to be white are.
She matured into a color that at casual glance is white. Upon closer inspection she is a pale cream color.
She looks fairly leghorn-ish to me, so I have assumed that she has a good dose of that in her parentage. And does she lay big beautiful colored eggs!
Hope yours turns out well for you, too.
