I had 7 cows ( my original herd-being raising for about a year) consisiting of all young bulls/cows: 3 jersey, 2 dexter, 2 angus. I recently bought out ( 2 weeks ago ) another breeder who had 5 dexters. I want to breed the dexters. The issue I am having is 1 of the new dexters is a 2 year old heifer and she is a terror to feed. She will attack the feed bucket with her horns when I holding it, I have turned my back on her and she horned me and tore my pants. At times Ive dropped the feed bucket and she kept coming and i fought her off by pushing back against her horns. the strange thing is without the feed bucket in hand she is sweet as can be and eats treats out of my hand. i hate to get rid of her because dexters are hard to come by in my area especially a heifer. Is there something I can do to retrain her behavior and protect myself.
