I don't think so. My RIR and SS have the green metallic shiny hackles/neck feathers and they are both pullets. I think it's the pointy hackles that indicate males.
I'm not sure if the neck feathers on pullets are called hackles though.
You need to tell us how old this chick is and the shiny, skinny saddle feathers are really a better indicator of a male than the hackles, but those sometimes are not really visible till they are over 10 weeks old.
*yes, the hackle feathers are still called hackles, even on the pullets.
