Hello,

I'm running a fence to protect our chickens.

Our current ( !! )  fencing is wire deer / sheep netting. Can I use this as my negative and then run positive lines as normal?

Rather than separate negative strand and relying on earth contact?

Cheers

Dave

short answer No

assuming it is working you will get a shock of the fence provided it is not shorted to ground
 there should be a spark that will jump an 8-10 mm gap
whatever you wish to deter must be in contact with the ground /soil .
So a bird sitting on the wire will no be affected  but anything else should get a nasty bite.
good luck

The negative (earth) goes to a rod driven into the ground beside the electric fencer unit.
The positive connects to either netting or single or multiple strands.these MUST NOT TOUCH the ground as you are relying on the predator (already touching ground) to touch the wire and complete the circuit (gets shock).
A single strand about 6" high may be enough if you already have fencing.
Best would be propitiatory chicken netting as here ............ https://www.electric-fence.co.uk/50m-voss-farming-electric-fence-netting-sheep-netting-90cm-1-spike-orange.html?gclid=EAIaIQobChMIzqvyxYSo4gIV7bDtCh1iqAAwEAYYAiABEgKk0_D_BwE

Make sure your earth is in deep enough and keep the earth damp.
As the other chaps have said make sure the wire carrying the current does not touch grass or growing plants.
We ran a special netting for chickens as George mentioned, and standard steel wire single strand for pigs.
Good luck

Thanks for the replies guys.

I have to run a couple more earth stakes as the ground is a bit stony and quite dry.

We have lots of problems with mink / stoats / martens, as well as foxes, deer, boar and when its a really bad winter ( according to my neighbour ) wolves. Never seen one myself but the Hunters plinked one a couple of years back about 20kms away.

While the larger animals should earth themselves, those pesky long bodied creatures climb the fence. What iI was hoping for was that as the little blighters climb the fence after avoiding the first low down +strand they'll catch the next one and get zpped as they are against the metal fencing ( -tve) . I would have to connect the fencing to a couple of stakes and the - of the generator.

Don't get me started about the birds of prey. Lovely to watch but really annoying when you see them flying off with your 1 month old restocks!

IF the thing you want to stop can touch the net & the wire then yes that will work.

Its just like holding both wires to get a shock.

It will be more powerful than using the ground too.

Blimey Dave, Wolves!

I'm guessing you don't live in Surbiton.

We looked after a chums sheep for a couple of days and found one scratching against a post thought the electrics were off a quick touch soon killed that illusion, I guess the wool insulated them.

The chicken netting was always loosing its omph by grass growing up. A wearysome task once a week taking it in cutting and putting it out. Happily we never lost out to foxes.
Friends had loads of problems with mink/martins, something we never had to face.

In Brittany stock control was all done by electric fence, virtually no barbed wire.

Thank you for the replies...I'll give it a go and see what happens.

Todthedog...most of the farmers here don't bother with anything fancy like elecktrickery.   They ring the grazing field with the cheapest fencing they can find and then deposit a couple of Spanish Mastines to stand guard.

They are magnificent creatures. Edit...the dogs [ not necessarily ] the farmers.

To the casual observer they look a bit lazy, always lying down or asleep or very slowly plodding around the perimeters....but by the dead! You should see them when there is a threat...their huge mass belies their speed and grace. They are formidable. Although my neighbours dogs can be bribed by a rigourous scratching of the head and ears!

We had a couple of pigs a while back, and we used a combination of electric fence which looked like sheep fencing, and rope with a wire incorporated (I guess Horse "tape" would be the same). Easy to keep the Rope off the ground / away from tall grass.



I've been meaning to put it along the top of our perimeter (Rabbit) fence, to keep the Deer out ... but perhaps a double strand a few inches apart, that could not "touch", would blitz any fence climbers?

Fitting an extra strand close to the top of the fence posts to deter ‘climbers’ is a standard ploy when an open topped pen is in use (think large rearing pens or chicken runs).  The 12g shotgun was the best deterrent, if reynard troubled the chicken runs, when Dad was alive.

High power mains units are generally better as a deterrent than the typical economy battery powered units.
