The color is difficult to see properly in a picture. She looks colored like a BB Red OEGB pullet, except for her legs. They are the wrong color.
She may be a Ginger Red OEGB, but she looks a little too dark for that breed in the pics. (That is why it is so hard to identify from pics).
Or she could be a mix from a Black OEGB & a BB Red or Ginger Red.
Anyway you got a really pretty pullet there. They have great personalities!
There are abbreviations for a lot of chicken breeds. Once you get familiar with a few different breeds, you will catch on to the abbreviations. I still have to think about the ones that not so common, & sometimes I have to ask too.
