Really hard to tell at this point. She is just a baby and isn't standing in any kind of pose. She does seem to be a nice cross bred heifer at this point. As she gets toward weaning age and on, she will change and be easier to evaluate.
Get her weaned on little feed and get a 5 gallon bucket and take pictures. Picture after picture get the right one. It take lots to get that one just right for us non professionals. Then evaluate her. She has the basics but looks green as grass.
