I just joined Backyard Chickens and have been raising chickens for 6 months now. We have just started getting eggs! We were letting our chickens free range in the yard while we are home until a couple of weeks ago we had a fox attack. Luckily, he only got away with a mouth full of feathers and our 3 hens escaped relatively unharmed. I feel like they are pretty safe when in the coop/small run because we have extra locks, two layers of hardware cloth and a 1 foot deep hardware cloth apron. We are looking for the best way to keep them safe, but also give them some more room. We were thinking about using the electrified poultry netting, but have some safety concerns. 1. Is it predator-proof/safe enough to leave the chickens in during the day if no one is home? 2. It talks a lot about shocking predators which is great, but I am worried about it shocking my chickens and also my 4 pound puppy. How dangerous is the shock to small animals and children? thanks!
