I'm a tad confused. So the mother of this chick isn't a Cream Legbar? If that's the case you won't be producing autosexing or sex-linked chicks. The CL rooster will pass the barring gene down to all his offspring so you won't be able to use head spots to sex. The chick in question does appear to be a pullet and the black sex-link chicks a cockerel and pullet
