I have a similar problem. What about roundup along bottom of electric mesh? Say a few inches either side and that'll stop it earthing.
For semi permanent fencing, I've used chicken wire attached to either metal hurdle spikes or 5 ft 1.5x1.5 inch stakes. Hurdles attached by slotting through netting, stakes with zip ties. Then leaving a ft gap, run a double strand electiric fence around. Round up round bottom. Corner strainers are either angle iron or thicker posts. By the time you've mucked around with electric poultry mesh, this goes up in about the same time. Yes, there are inherent flaws to this method, no it doesn't look as good as permanent fencing nor as taught but it goes up pretty quickly and can be moved plus it works very well. something that works and doesn't look crap.
