Well like you said, that right hind leg looks like an issue. I dont know if its just the picture or what, but the profile pic makes her look really unthrifty, has she been wormed recently? Its hard to tell, but from where the shadows fall on her sides it looks like she is really sunken in and looks like you can see some of her ribs, may just be the the picture or something...hard to tell. I am not trying to be mean with anything I am saying you are asking for opinions so I am going to give mine. She looks fairly growthy so she may have a future in a commercial herd, looking at these pics I dont think she has a ton of potential for a purebred herd, but some of them will fool ya, she may produce great ones. But on to my opinion, I am really tough on heifers/cows structurally, so having a structure problem and not really wowing me anywhere else, I would probably send her to the salebarn. But that is my opinion and what I would do if she was in my herd.
