Sexing chicks by feather growth?

[LoneCowboy]

Can you sex a chick by how fast their feathers grow? I have 2 buff orpingtons. Both were hatched the same day. One has really long feathers on it's wing that are closest to it's body, and one has really short. Does this tell me what sex they are?

Check out this site and the pics, Deniece. Feather sexing can't be done on all breeds and I'm not the one to ask about it, but this is a nice site.
