My rooster is a Black Orpington. My hens are various other breeds, including Buff Orpingtons, Easter Eggers, White Rocks, Red-Sex Link, Cuckoo Marans, Sliver Laced Wyandotte.
Black is quite dominant over most colors if the birds are all purebreds. If you use one of the chicks from this flock, even if black, you have a greater chance of other colors next time.
Buff eggs will hatch out black.
Easter Eggers: Most will be black or blue unless one of your hens is white. If the hens have gray feathers, then blue is a possibilityin their chicks. Sometimes you can't tell blue on the chicks because it looks black for a while.
White Rocks: Could be white w/tiny bit black flecks if the hens are pure dominant white. If they don't carry dominant white, but instead carry recessive white, you could get barred or other stuff, depends on how the breeder bred the white rocks. White Rocks can have both recessive and dominant white.
Red-Sex Link: It depends on the breeds used to make the red sexlinks. If your red sexlinks have whitish tipped tails, then some of your chicks could be white or white with little black flecks. If the tails of your red sexlinks are red with black tips, then you'll probably have black chicks.
Cuckoo Marans: Black or barred (cuckoo). Barring won't show up for almost a week, though you may get a white spot on the head at hatch???
Silver Laced Wyandotte: Black
That should give you some idea since your chicks are hatching as I type, though I could be wrong on the finer points.
Happy hatching!
