The only way sex linking works is with a barred (cuckoo) hen and a solid rooster. I believe the barring can be under any color (black cuckoo, blue cuckoo, splash cuckoo). With any other combo (non-barred splash hen, cuckoo rooster, two solid parents) the offspring won't be sex-linked and any...
Do you know the colors of the parents? If the hen was cuckoo and the male solid, the sex link should work and this should be a hen. The comb development is suspicious but it's still pale so it could still be a girl.
