JackE, what are you using to keep the grass down under the fence? Our current plan is to run our sheep/goats through first to get the grass ate down then put our chickens on and hopefully only have to move the fencing once a week. Do you think that would keep the grass low enough so that is doesn't ground out the fencing too much?
I use Roundup for the perimeter of the fence. If I was moving the fence around the yard, I would just make a quick pass with a lawn mower. That's what I did for a while when I first got the fence. The fence is easy to move, as you can just pull it out of the ground, move it, and step it back in. But since my fence is never moved, and I have all kinds of other things to be doing instead of moving a fence and mowing a stretch of grass every week, I just went with the easy fix of Roundup.
Maybe with the goats and sheep, you'll have animal lawn mowers that can keep up with the job. If they eat where you need them to.
