Sexing 7 week old tolbunt polish...red noses?

[szczur]

Any signs showing of what gender these chicks are yet? Most of them have bright red above the ridge of their noses. Is that an indicator they are cockerels? The four red nosed ones also have smaller head poofs, so I'm thinking I have 4 boys and 2 girls. :/




The last pic is the suspected boys in the middle and the suspected girls on either side.
