Black copper marans: pullet or cockerel?

[Criticalicious]

Pullets will have varying amounts of copper around the neck. On some, the copper is barely noticeable

 

[Hensndoes]

^^^ marans vary in copper. One of my best looking FBCM hens has hardly any. That’s quite a tail on yours. She also appears to have pencilling on her feathers. Where did you get them?
