I run a few head of cattle on 100 acres and currently have 3 horses. In past years I've had negative experiences with horses messing with my new mama's and their calves. Two different horses caught stomping calves and fighting new momma's (one gelding, one mare), seperate occassions. Sold them both and swore never to have horses again. Then a friend needed a place to keep his horse, so I said okay. I caught the horse running the cows. Someone said it is because they are alone and need to be a part of a herd. So I ended up with 2 more horses (1 gelding, 2 mares) and all three have been getting along fine and keeping to themselves leaving the cows alone. Until today, my son caught my friends 4 year old gelding pawing a new calf and kicking and biting at the momma. Has anyone else had this problem with keeping horses and cows together?
