I’d think you’d have better luck with garden pest reduction by just letting them in your garden. Bugs don’t stick to the perimeter of your garden. I was concerned about my flock destroying everything, but the are surprisingly considerate. Even sticking to running down the paths when returning to their run. LOL. They steal a few low hanging cherry tomatoes or blackberries and maybe nibble a few leaves I’d prefer they leave alone. But I let them have an hour or 2 every evening in my 50x80 garden and have no regrets. I just plant enough extra knowing i’ll lose some stuff to them. It’s a small price to pay for all the bugs they eat, including every last japanese beetle last month. Then again, my garden is not going to win any prizes, but I’m Ok with that. Just something to consider before going to the trouble of a tunnel or moat.
