I've got three chicks that I'm unsure of the breed. I've got fairly good at telling the breed of older chickens, but these little ones have me stumped. All three were bought at a feed store, are likely from Ideal, and were organized as "Assorted Heavies". Someone at the store removed all the labels giving possible breed types, and the woman that helped me didn't really seem to know what they were. I'm not really concerned about sexing them at the moment, but if there's any insight, that'd be great. All three are about a week old.

Employee at the store said this guy might be a game bird of some kind. It's mostly black, with pale yellow on the face and chest, and bright white tips on the wings.

Feed store said might be a brown leghorn, but that it stands up too straight for a leghorn? This is a busy little bird.

This one looks sort of yellow in this picture, but is actually much closer to a cream color in person. The newest feathers on its wings have silver and brown tones. It's hard to tell from this picture, but there's no coloring on the legs.
Thanks for any help/info! Sorry for the big pictures...
