Tell me about it,. good for nothing but trouble. I know most people in the States that raise them use them for clearing the land. Do they have that issue in Australia? ie, environmental degradation due to herding?
Basically, goats don't have as much of a herd mentality. An example of why they are hard to farm is fencing. Normally, when fencing a paddock, you would put a inwards facing corner post in each corner, to hold up the fence. But with goats, if you do this, they will climb over. They are also more aggressive, or at least less submissive than, say, sheep. And they chew on anything and everything, IIRC. So you can't irrigate a paddock with goats around, for example.
