On the sexing threads people are always saying that certain chickens, often Easter Eggers, have a female-specific pattern or a male-specific pattern -- which apparently they can ID even though those birds don't have breed standards.

Don't photos for this contest...
It may be too late for this contest, but it would be awesome if someone with the specific knowledge and the necessary library of photos would compile a photo guide to sexing birds based on male-specific and female-specific color patterns.
I think I've got the hackle and saddle feather thing...
