Looks like a RIR to me but im new to chickens...i would give a quick google search of "Pictures of Rhode Island Reds as chicks" or something like that and compare pics.
Thank you for your thoughts on this. It's really neat to see how her feathers/patterns are developing. She was a light honey brown when she was a "baby."
Here she is on the left, next to the one I believe to be a RIR. Their coloring is similar, but the one on the left also has the black/additional patterning.
