new 3 year old mare

Question
i have a 21 year old mare that i've had for 4 years. she is absolutely sweet and the most loveing horse i've ever had. and about 3 days ago i bought a new 3 year old filly/mare. and my older mare hates her and bites her and wont have anything to do with her. so i don't know what to do about that. and i want to start working with her. she nips and pushes into people. and wont lift her feet or anything... so i need to work with her. and on her front left leg is bowed out at the knee so i was wondering if corrective shoeing could fix it??

Answer
corrective shoeing won't fix a horse that is over at the knee. Your older mare will settle, she is just showing the young one whos boss, perfectly normal for strange horses. If you are going to work with be sure to take her out of the paddock where the other horse is as she may take to her not knowing you are there and get you hurt. Good luck.
