A good fence goes a long way.

My neighbor just texted me telling me a dog was seen killing his chickens. I went outside quickly to check, brining my rooty tooty point and shooty and found the dog eye balling my fence. The fence is the galvanized steel fencing so nothing super fancy. It is secured every 8ft or so to posts, and surrounds the 1.5 acres for my chickens. If that fence wasn't there I was certainly going to be out several chickens. The dog would've tripped cameras but I would have lost valuable time getting there.

Long story short. If you're thinking about getting fencing for security against animal for your animals safety I highly encourage it and will never get rid of mine. It obviously doesn't stop all threats but it's so worth it.
