I've been looking on line and consulting chicken books, but can't find a very clear (to me, at least) description of what the term "partridge" means in terms of color pattern. I've seen pictures of what look like a bay color with black lacing, but others that look quite different, still called "partridge" whatever - rocks, wyandottes, etc. Can anyone clarify? Pictures would be awesome. It's too late, anyway, I already ordered some "partridge" rocks... but curious and interested. Thanks!
