I have 7 babies I bought from Rural King. They got them shipped in from a hatchery in a Heavy Assortment Mix. I Thought they were whites and a couple of buffs, but the feathers are coming in multi-colored. Some are white with black and brown marks that kinda resemble partridge coloration and the other two are buff, white, and have the "partridge" markings. What color are my naked necks?
