could this color be sex linked?

[dekel18042]

I have my very first day old peeps. Some of the peeps are pure black (two look sort of very dark charcoal grey...maybe blue?) while some have definite white splotches on their heads.
Mothers are black Jersey giants.
Father is a Delaware/aracauna cross
Could this be any kine of a sex linked pattern? I'm going to watch to see who develops into what.

(and no, I didn't do this hatching trying for sex linked anything, but it would be interesting if it were. I just used the eggs I had to test my incubator. I really expected all black chicks, not the spots on some of the heads.)

As far as I know, they are not sex-linked. Only certain crosses (Rhode Island Red rooster or other "red" bird with black bird, Rhode Island Red rooster with a "silver" bird like White Plymouth Rock, etc) will produce sex-links. Araucana crosses, which are Easter Eggers, often produce chicks of varying colors, as they themselves are mixes.

Thanks, so I can still hope for all girls? (dream on)
