Black Star sex-link chick getting white feathers

[Hreamy19]

Hello there! New chicken mom here. One of the chicks we selected is a Black Star sex-link. It was with a batch labelled 'pullets', but I realize that the sexing of baby chicks is only about 90% accurate. I was reading online about the breed and read that with this particular breed, the males will develop with bars on their feathers but the females will stay all black. This chick is a bit bigger than the others we purchased at the same time, maybe 1-2 weeks old, and it's wings are feathering out. I'm seeing white edges on the feathers and now also white on the throat/chest area. Is it to soon to decide it's a roo?

Sex linking is actually 100% accurate, not 90% The 90% figure relates to vent sexing, but the way sex-linked chicks are bred is such that males and females hatch different colors, and that's 100% accurate. A male black sex link would hatch with a white spot on its head and the feathers would be barred.

If this chick is a black sex link, it's definitely a pullet. It's not uncommon for black breeds to feather out at first with some white wing feathers, but they molt these out. I can't remember if my BSL chicks in the past have done this. It's always possible the hatchery mixed up another black chick with a BSL, but if this chick is indeed a BSL, it's definitely a pullet, since it has no head spot and isn't barred.
