The lady you spoke to probably meant that your chicken is a Production Red, an breed that originally came from crossing Rhode Island Red's with another breed, although I can't remeber what right now. If she is that smart and friendly, consider yourself lucky. The one I have is skiddish and dumb as a doornail (see my one of my other posts for a description of what it takes to get her into the coop at night, and yes, it is still going on). I love her all the same, and am waiting for the day she beigins laying like yours is! What part of the country do you live in? I am in Florida, and down here we do have flocks of feral chickens that survive just fine on their own, no coop needed. It might be nice for her to have a little sheltered area for rain, though, and maybe some food and fresh water. She certainly sounds "plucky"!
