Ok, I hate to be this guy, but what do I have here?

Went by our local Rural King a few weeks ago to get feed and while we were there this little one and 3 others were in their “mismatched” or leftovers bin. All of them had the worst pasty butt I’ve ever seen so I couldn’t leave them to just pass without a chance.

Of the four chicks I’m pretty sure one is a lavender Orpington, one is a cream legbar, and the other is a jersey giant. But I have no idea what this one could be. At first she was just all chocolate fuzz, then the gold tips on her feathers came in, and now the feathery feet. Any insight on her will be greatly appreciated!
