Is it normal my 12 year old niece develop big boobs? She said she's self conscious and concerned about the boys at her middle school?

Yes, it's normal. For girls, puberty generally starts sometime between 8 and 13 years of age, and breasts begin developing at that time. The size varies from woman to woman. Some girls will have small breasts forever, some will be large. Weight and body fat also affect breast size.
