9 week old chocolate orphington sexing help

[fishnmama]

Hi all I have 2 chocolate orphingtons that are 9 weeks old and I can't tell if they will be hens or roosters. They look like hens to me because of the body shape but chick 1 feathered quicker and had more of a tail than chick 2 and still has a bit more of a tail than chick 2. Thank you for your help!
