Once they start killing calves, they'll keep doing it.

When I lived in Troy, there was a guy who owned some land near Goshen. He was a sorry excuse for a cattleman. He had a pasture full of inbred Charolais cattle. Two and 3 years of calves in the pasture with the cows. Anyway, the farm was across the road from one of the chicken farms I checked on. I was at that chicken farm one day and saw a cow trying to calve. The buzzards were sitting all around her. As soon as that head appeared they got the eyeballs of the calf. They then started in on the cow around the calf's head. That caused the cow to prolapse, then they started pulling the whole repro system out of the cow and eating it and just got worse from there. The chicken grower took out his deer rifle, shot from his place, across the dirt road and shot the cow in the head to put her out of her misery.

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land. 2 Chronicles 7:14
