WING BOW FEATHERS and Roos, How do you sex?

[chickenguysmom]

Would there be any difference because these are all banties?

These chicks are 2 1/2 weeks old but seem to all be feathering out at the same rate with the exception of the silver penciled rocks which are feathering out VERY SLOWLY.

Wings now are completely feathered on porcelain d'Uccles, mille fleur d'Uccles and Ameraucanas, back of necks are 1/2 way done and on chests the milles have both chest lines meeting in the middle. Also, milles have backs that are about 3/4 done, and porcelains are about 1/3 to 1/2 feathered.

Do bantams feather out quicker? Because by their actions (long necks, not cowering) orange/pinkish combs, bigger combs, play fighting, giving my hand the 'stink-eye' with the hoppy-hop when I pick them up, etc..... they all appear to be roos.....

I am beginning to think I have at least 12 out of 15 that are cockerals. The only think I am pinning my hopes to are the feathering/wing bow feathers issue..... everything else says BOYS!

I think what made the UC Davis guidelines work so well for me is that I had all one breed to compare. When you have 16 that all look alike, feathered out nicely, and 5 that aren't it's easy to pick out the cockerels. I correctly indentified my 5 roos at 5 weeks old.
