Porcelain D'uccle gender help?

[Wurmbag]

I have three porcelain D'uccle chicks and I cant for the life of me tell whos a roo or hen. All three are 8 weeks old. when they first started feathering I thought the first two (pink, blue) were hens and the last one (orange) was a roo but the older they get the harder it is to tell.
