In that case, the Easter Egger chick is probably one of the ones that you had thought came from a Speckled Sussex (the chick with the pea comb.)We only had one egg from the easter egger (green). All of the others were shades of brown. Can't remember if there was a white one. But am positive only 1 green egg.
And the chick you had thought came from the Easter Egger would actually have come from a different hen. I'm guessing he may have the Rhode Island Red for his mother.
