This protective enclosure for the garden uses chickens as an effective garden pest control along with a moat to protect your crops.
A chicken moat is not a waterway, but it does provide a protective enclosure for the garden. Weeds, insects, rabbits, ground hogs and even deer are barred from entry by the double wall of fencing and the ever-diligent patrol flock. All in all, it’s a clever solution to the fowl raiser’s dilemma of whether to fence the birds or the garden: Fence both!
In days gone by, rulers of kingdoms would protect themselves by ordering a few thousand serfs to build a moat around the family castle. With the current shortage of serfs, the practice has fallen out of favor. However, when faced with that classic country conundrum, “Do I fence the garden or the chickens?” I decided to make a modern adaptation of that medieval practice. I fenced both fowl and crops with a chicken moat.
My moat is simply a strip of dry land, enclosed by two parallel fences, which surrounds my family’s garden. Throughout the day, the hen patrol moves all around the garden (but never in it), munching on all those things hens love: weeds, seeds, worms, tiny pieces of stones, and (best of all) bugs.
