The steer calves, with one adventurous sow.
You can see the two-strand electric fence. In the industry we refer to this as a psychological fence. Hogs and cattle are easily trained to electric fence. The fence around the other lot is a physical fence, with five-foot high cattle panels and two boards, attached to wooden posts.
While I hate to anthropomorphize and say they’re friends, I will say they’ve gotten acquainted.

That is THE most beautiful pig I think I have ever seen! What does she eat? Is she organic?
Thanks, Diana. No, our farm isn’t certified organic.
She eats five pounds per day of a corn/soybean meal/ vitamin and mineral mix, which I grind and mix on the farm. What’s interesting is the amount of time the sows are out rooting around in the dirt and eating the calves’ hay.
