Most folks on here put a hardware cloth (fencing) liner around the bottom two feet of their chain-link run, and some say to put more fencing on the ground to keep predators from digging in. Do you put the fencing on the ground INSIDE the run, or around the OUTSIDE of the run? Thanks for your answers, we were given a couple of unwanted ducklings and have a 6ft tall chainlink dog kennel (10' x 5') for them so far, with more territory and a pond to come soon. They're about 2 months old now. Thanks!!!!!
