I am going to start using some electrified netting to graze my birds (and pigs, goats, turkeys) and am trying to decide on an energizer.

I see most units that run off of AC are "constant", sending something like 900 volts. Then most units that run off DC and/or Solar, use pulses every second of much closer to 10,000 volts.

What are folk real-world experiences and opinions with these two types?

I want the most effective deterrent for the birds and hogs. Lemme know your thoughts!

Thanks

I grabbed enough netting to enclose about 1600 sq ft last fall. The energizer I have is the pulse-type. It generates in excess of 10k volts. I keep my birds inside the perimeter and move the fence every 30 days or so. (I have 25 chickens, 4 turkeys at present). The fence seems effective at keeping my dogs out. They are fairly large dogs, about 80lbs each. In fact the dogs after a zap or two won't even cross the driveway near the fence. The birds on the inside rarely if ever get zapped. They are happy with their forage space. The fence is 42" tall. They could clear it easily if they were of a mind to, but seem most content within the confines of the fence. I've had birds go over the fence twice. When the wind blew shut the coop door and evening approached, 3 of my chickens jumped the fence to try to find another way in to roost. Introducing 2 new turkeys to the flock last week, the new birds jumped the fence to hang out with their new flock rather than wait for me to introduce them.

Personal impression of the zap: When I'm wearing rubber-soled boots, the zap is clear but mild. In thin-soled shoes, the zap will cause my arm to jerk mildly at the elbow. If I kneel in a puddle and touch the fence, the entire side affected side of my body is thrown a bit. (I don't recommend this latter test, it was a surprise and a bit of a revelation to me).

I've only this one set of experiences, so cannot compare it to the always on. I use a solar energizer and it has been doing remarkably well as far as I can tell. The primary predator I'm concerned with is dog. My dogs respect the fence well.

Both of my fence set ups are pulse chargers with electric netting. I've kept chickens, ducks and pigs with no trouble as long as the pulse was up to at least 5000 volts. Below that and the chickens seem to tolerate it enough not to fear it. I'll also note that young birds will squeeze right through most electric netting without even getting the jolt. Their light weight and feathers create enough insulation to prevent the shock. The good news is that they eventually grow out of that and stop trying to push through. Then they try going over it. If you've got a heavy breed of bird, you'll be ok. They tend to grow out of the flying stage quickly, especially if what's on their side of the fence is better that what's outside of it.

I don't think that electric netting is meant to be used with constant flow chargers (unless I missed something). I thought there was a risk of melting the plastic netting with hot wires.

We use 3 sections of electronet from Premier Fencing strung together, and have a charger that can take A/C (via a wall wart) or D/C via clamps. With the A/C it gives you enough of a jolt to think twice and the pulse is about every second, so anything trying to work through it would be quite unhappy. With the battery, it works well initially but the light will still be pulsing, and the shock delivered drops way down. You jut need to keep rotating through deep cycle batteries if that's what you want.

We have an older solar fence charger here that needs some retrofitting, and we'll probably get to that this summer and give it a whirl.
