Does a minor automatically become a Naarah at age 12. What if she does not bring two hairs till say age 13? Does she have any rights at age 12 (e.g., Miun) without proving puberty? Also is a Bogeres automatically a legal Bogeres at 12-1/2 or does this too depend upon her physical development?
Na'arus starts with Simanim, not with age, Bagrus is six months from the onset of Na'arus.
