I'm not sure whether your chick is a boy or girl, but it does have similar coloring to one of my EE pullets. I always thought mine might be a rooster because she was so much larger than the other 2 EE chicks, had different coloring than they did, & had a wide 3-row pea comb whereas the other two had narrow pea combs.
She's still the largest, her coloring has changed so that she's almost a twin to one of the others, but her pea comb is still huge compared to the other two. Despite her comb, she still ended up being female. Here's a link so you can see her as a chick, pullet, and hen - at the bottom of the page you can see the difference in their combs (Pippin is the one I'm talking about).
