Finally captured and weaned all our spring calves. Our feeding lot is broken up into three joining paddocks: the barn lot (very secure 5 board fence), a middle lot (woven wire fencing), and a pasture lot (6-7 acres with 3 strands of hot wire). I usually wean calves in the barn lot for a week, work them, run them out into the middle lot, and then after another week open up the pasture lot. I had all the calves except 4 heifers caught and released all the way into the pasture area. I finally caught the 4 stupid heifers on Sunday evening and had them in the barn. This evening I went to feed and found that the heifers had run through the board fence, destroyed the gate into the pasture lot and ripped down the electric wire. Now all the calves (70 total) are all scattered back out on the farm.... Now I'm back to square one.
