I have a little over half an acre that I would like to fence in for a pair of goats. I have already have a fair amount of hoq wire that is 42-48 inches tall and has 6x6 inch spaces in the wire, however I have read that goats will get their horns stuck in this kind of fence. Is this a serious problem? Will they jump over this fence? Is there any other kind of fencing that is fairly cheap that I could use? Preferably around $150 per roll?
