Hi, I've been looking into electric fence as a way to keep hens in the orchard. Our hens free range near the house, where there are plenty of dog and human smells to warn off the local raccoons. Down the hill, in the orchard, we have lost a two hens, though. Here is an interesting link by an electrical engineer who caught the chicken bug: http://www.rawpaleodiet.org/bird-sanctuary-1.html and a price sheet, I came across: http://www.kencove.com/fence/Electric+Net+Fencing_products.php Getting power down to the orchard is another concern, but I'm done researching for today. Since there are no chickens in the orchard, I've got to go mow!
