I bought these eggs on ebay and when they hatched they all appear to be purebred Dominiques except for one. It has the spot on its had, and light feet like a female, which are Dominique characteristics. But it is grey, not black. Thoughts? Is this a mutt? Will it look like a regular Dominique as an adult? The pic above is an accurate pic of his true color. The one below everyone looks a little lighter than they really are. The black siblings are really black not greyish.
