Sex link errors

[Adolfo11]

Hi all. A silly question, but I wonder what the error rate is on sex link chicks? I know regular attempts at sexing has a 10% or so error rate. I would assume that doesn't apply to sex link, but don't know. Thoughts?

Since they hatch different colors, there's no way to make errors

No, I get that the color is suppose to give the sex away, I just wonder if the color is wrong. In other words, a cockerel comes out the color of a pullet?
