Could the first ones be a self blue/splash mix? The owner calls them "pearls"
And the second ones are the only "chocolate" color like that I've ever seen.
Great site! I been here a few times poking around and decided to join up! I have recently (in the past 6 months) bought a few chickens. I've got all bantams now: BB Reds, Japanese, and Silver Duckwings. I am raising 11 so far out of my Japanese Rooster and little mixed hen.
