Sorry to take so long to get back to y'all. Busy day at the car lot.
On electric fence by what I know, which is admittedly not everything, but I use it on my own 4 acres, have hundreds of birds at times, hogs, dogs, cats, children from a newborn due in June, a 3 year old, and 6 from 12-18.
1st, pulsing electric fencing should not harm other than a very unpleasant jolt that will make a child cry but not need a trip to the hospital. I am not saying if a child has an arhythmia that it cannot cause problems or even death, or that is some weird case that they got tangled in it...... get the picture?
I have personally peed on the electric fence and it hasn't reached out and touched me so to speak. Go to snopes and check out the legends.
There is no way in hades I would use netting to electrify an entire acre or more. In fact, I wouldn't string together more than 2 of Premier's fences together, because I am the one that has to move them.
In fencing, these are the basic options that I know of.
1. Locust posts and woven wire. Permanent, but can be dug under.
2. Barbed wire
3. Chainlink
4 Electric
5 Electric netting.
About electric fencing, both netting and regular- Animals need training. Electric is NOT a physical barrier but a psychological one. Even after training, if an animal is frightened, they WILL go through it.
About a 1 acre tract. What I would do, not that I am telling anyone what to do, but with my finances allocated to the farm, this is what I would do and what I am doing with my 4 acres.
I would fence the perimeter with regular electric fencing. I have a 20 mile charger (electric) that is adequate for the job. I run a 2 wire system but I have hogs, sheep may be different. Mine will be created with rotational grazing in mind with several quarter acre lots made adjacent to one another with electric fence gates. I would use the electric netting as moveable fencing for the poultry and or the sheep. I would also have a training area which is a small area of woven wire permanently installed with electric inside it with colored tape tied to it at 3 foot intervals.
When training the animals, they go into the small enclosure. If and when they see the electric fence they will nose or back into it. When it shocks them, they have 2 options- back up, or go through. The woven wire, or in my case, a stall, prevents them going through and they learn to give the electric wire a wide berth. It doesn't take long. I wish I had pictures of the jailbreak I had when I didn't train my hogs lol!
IMHO, electric is the cheapest to go,
