I have just bought 5 black angus / brangus heifers and one of them apparently doesn't like it's new place. She has been out at least 7 times in the past month. She is between 3-5 months bred and shows no respect for fences. If it doesn't break on the first hit, she'll back and run at it again. Having a tough time deciding to sell her or keep her. She is probably the second best looking heifer I have and will probably throw a pretty calf. Last night she made it about 2 miles down the road into a neighbors herd. Any recommendations to keep or sell.
