Wut r your cowz? Large frame, small frame, straight English bred, exotic cross? Makes a big difference. Too much power running clubby on clubby can lead to wrecks. Walks Alone and BIM on straight bred or F1 usually works ok.
I presently have a BIM heifer I am going to show as a market heifer and she is definitely the most flighty, nervous heifer we have ever had and it's always an uphill battle to get her to eat. Too straight on both ends too. I personally won't ever be buying or using him again. Just something to think about. Muscle and hair are definitely two things she has going for her though.
