My black star ("Halle") is really curious and friendly too, and she likes to peck at my legs and toes to get attention. She's the only one that does this, it hurts. I give her a 'peck' on the back and that usually stops her for a while. She's really mouthy and bossy, if one of them is being loud it is almost always her.your Coca looks like the one I call Star. (At my house, chickens only gets names if they are friendly, otherise they are just "the girls'. ) We also have a Buffy the BO.
Our black star we got a couple months ago is super-friendly and curious, she just loves to be held and petted- no wing-flapping when picked up. I took her picture last night when we did the big coop switch. She's just a nice, calm hen.
