Speckled Sussex gender - 6 weeks

[CarrieShields]

The farmer where I bought my four speckled sussex chicks says he is 90% accurate in sexing SS chicks, but 3 of the 4 look like this (significant comb, white chest) at six weeks old. The fourth one looks very different. Any chance this "hen" and the other 2 that look the same, are girls?

With that much comb I would say cockerel.

Welcome to BYC!
It appears to be a cockerel.

I also say cockerel, my oldest SS is 10.5 weeks and doesn't have half that comb
