Black Sex-Link Down Confusion

[Blackberry18]

I know...like my tenth thread on Sex-Links, but I have to get it cleared up.

So, on male Black Sex-Links chicks, does the white spot have to be on the head? My friend hatched out a Black Sex-Link (which she unfortunately had to gas it because it had some fatal deformities), and I had thought it was a male because it had a white spot on it's chin, but she said that it was a female because the white wasn't on the head. So, can female Black Sex-Links have white, but the males have to have on the head? Thanks in advice.

I'm sorry to hear about the chick.
