We have a cow about 8 years old who was open year before last and this year she aborted. My question is this. Has anyone had a cow that absolutely thinks she is a bull. To the point that she fights with our bull and won't let him breed the other cows. She tries to fight the neighbors Bulls. Bellowing all the time and throwing dirt at them. she isn't mean or aggressive to us. Even walks with the kids down the road and back. She refuses to let the bull breed her as well
