I have a gold laced Wyandotte named Coral and she has zero sickle, no larger comb than her sister a silver laced named Blossom, but less lacing on her wings (which i heard was a male trait), and if the light catches her back feathers they are a bit shiny green. doesn't act like a cock, she is about sixteen/seventeen weeks old and exhibiting no crowing or trying to mate or aggressivness. Thoughts?
