Brown leghorn chicks, how to tell gender at a few days old

[FrahmChicks217]

I keep seeing conflicting information on if or how to tell what sex brown leghorn chicks are. Does anyone know how? I bought 15 from a neighbor but he had no idea how to tell them apart.

Used to breed/raise/show light brown leghorns and was never able to determine gender when they were chicks. @ The Moonshiner do you know?

Oh I do know but at best it only worked correctly about half the time so...
Eye stripe... females, darker, more distinct and goes all the way back.
Males, lighter not as defined and fades out after eye.
Same kind of thing with the arrowhead on top up their head. Females usually darker and has more definite edge. Mills just have a more faded overall look and not a crisp edge.
Outer stripes on the back. Same, females have nice distinct outer two stripes and nails are more faded.

I'll attach some photos of around the eyes. Hopefully they aren't too blurry as these guys don't like to sit still.

Honestly, there is no sure way to tell at this age.
