I have a 7 year old simmental that looks at me like that when she has a new calf , I've had her 3 years now and she's always been nasty to me when she has her calf , this time I was in to feed her and she came and me and the feed bucket went flying, neeedless to say didn't get any grain that day , her calf was doing good so I let them out with the others. She is one of my best looking cows and always raises a nic calf but I'm getting too old for this, after this one is weaned she's getting wheels
