I've had chickens for a year now in a rural neighborhood. As such my former set up was a three sided coop attached to a movable poultry netting run. I've had no issues with predators even though I've seen a possum in the neighborhood. Last Thursday a neighbors pack of dogs broke down the poultry netting and killed half my laying hens, and injured my rooster. I had 13 little 7 week old pullets in a separate more secure tractor. The dogs pulled the wire out of the wood with their teeth. Thankfully I did not loose any of the little girls since they all escaped with only one major injury. Animal Control was called and the neighbors were issued an abatement order, I moved my chickens into a horse stall at my parent's farm to protect them while I take time to rebuild and lock down my security. My current plan is to fence the entire backyard with no-climb wire and still keep the same interior setup, does anyone have anymore suggestions? Should I run an electric wire across the top and bottom as well?
