Large White Cochins (yes all three) - the one on the left is what you normally see in the White Cochins (yellow chick with gray back), the one in the middle is light black, and the one on the right is solid yellow.

Same three chicks, the light black chick has racing stripes down his back.  The colored dots on their heads are Sharpie markers which I use to ID pen numbers until they are old enough to wing band.
