If you've had chickens for a while, you loathe raccoons. If not, you will. Here's why:

A while ago we started losing 1-3 chickens a night. Some were completely eaten, others barely touched. This is one of the more infuriating aspects of predators: they don't have an "off" switch. Instead, they keep killing until they run out of targets.

In the wild, their prey scatters and the predators only get one or two victims. But a fox or a raccoon that squeezes into a closed henhouse will kill your entire flock.

That's one reason I use open housing — no doors, and one side open — so the chickens can scatter. (Open-front housing has other advantages, which you'll see when you read Fresh-Air Poultry Houses.)

How did the raccoon get in, in spite of my electric fence? Different ways, it appears. There was only one well-defined game trail, but when I adjusted the electric fence so that anything using it would surely get zapped, the losses continued. Raccoons have no fear. A dog or coyote that gets zapped by an electric fence will never come near it again, but raccoons will prowl it endlessly, looking for spots where it can squeeze under. They can squeeze pretty flat, and if you put the fence wire too low, it shorts out. Farming sounds so easy! But I'm sure  you agree that farming is no panacea.

When adjusting the fence didn't work, I set snares. Snares are pretty easy to use, and by placing them only on game trails heading towards your all-night chicken buffet,  you can see how they can be very selective,  nabbing only the miscreants. After a few nights of nothing, we caught a single raccoon. And the losses stopped.

All that carnage from one smallish animal? Don't tell me Nature is kind!

In the bad old days, there was a Federal bounty on just about anything that moved, including raccoons. And old-timer told me that the bounty and the price of pelts paid for his pack of coon hounds. One result was that chicken and sheep farmers had little to fear from predators.

When the bounty dried up in the Seventies, so did the hunting and trapping, and the raccoons, bobcats, and coyotes became an ever-increasing threat. Even since I started raising chickens in 1996, things have gotten much worse. Benton County keeps cutting the amount they're willing to chip in as matching funds for the Federal predator control program — which only targets animals that are actively killing livestock — with predictable results: If you don't learn all about electric fences and snares,  your chickens are goners. It's almost as bad in town as it is in the country!

Keeping predators out of daily-move pasture pens can be difficult, since predators are motivated and can dig their way into the pen. Some things that help:

• Having a dog close to the pens. I'm told this always works. We haven't tried it.
• Electric fence surrounding the area with the chickens. This mostly works. See my Electric Fencing FAQ. Most people think that electric fencing has to be way more elaborate that is really the case.
• Electric fence wire on the pen itself. Does anyone do this but me? Hammer in a few nail-on fence insulators around the perimeter of the chicken pen, about four inches off the ground, add wire, and attach to the fence charger of your choice -- possibly a battery-powered one attached to the pen itself.

These precautions are fairly effective, but sometimes you get a predator who isn't afraid of an electric fence and wreaks havoc in spite of it. I'll talk about that in another post.
