Breed and gender guesses please? Bantam bin frizzles

[McGill]

2 yellow ones (guessing they'll be white or buff?) and a black one. Black is about 4 or 5 days older than the whites.

One black frizzle Cochin cockerel. Two white frizzle Cochins that are too young to sex. They aren't looking suspicious at this point, though.
