I've never tried to take a picture of a good cussin'. I swear that's what keeps my four in these days./w3tcompact/icons/laugh.gif The gate to the shop is twenty six feet across. It's usually open when I'm around. Visitor's heathern kids will see the goats and it's like the kids all of sudden morph into coyotes. The goats will run right at the open gate with them heatherns from heck on their tail. At the last minute the goats will veer left of right like there's this big ugly fella standing in the middle of the driveway. Folks ask me why they do that. I have to tell them the truth. That last cussin' was so memorable that even I still remember it.
Goats are like deer in that they won't jump over a fence unless they can see exactly where they're gonna land on the other side. As you might have noticed completely the opposite of humans who are rather fond of jumping and then praying like crazy for something soft to land on the other side.
Actually you will find keeping them isn't such a matter of how high the fence but how good the fence is along the bottom. A good test of your fence is to put meat on the outside and turn your minature dachsund loose to go after it. If the dog can crawl under the fence then you can bet the family farm and the kid's college fund the goats can too. You would think they were bunnies more than deer the way they can crawl under a fence.
A hot wire works good. Two of them work even better. One about eight inches or so off the ground and one about two feet works great for pygmies. Home Depot or Lowes both carry field fence in three hundred and thirty foot rolls for about eighty bucks. It works great if pulled tight.
I wouldn't recommend chainlink unless it was put in properly. The reason is chainlink fence is woven. That means it'll stretch, sorta on the principle of nylon pantyhose. You can put twenty gallons into a three gallon container and have it look like there's only ten. A bud of mine lost all of his goats to their ability to crawl under his six foot chainlink fence. No one had told him why there's that nine gauge wire along the bottom and why the chainlink is hog ringed to it every eighteen inches.
I highly recommend goats. They mow clean, love poison ivy, fertilize in as nonoffensive manner as is possible, and have personalities similar to good grandkids. Except for billy goats after six months of age. Then they're more like your own kids were or will be.
