Yes, their feathers or down in chicks do insulate them. I use electric netting. Until they get too big to fit through the holes chicks walk through with no shocks. If their beaks or feet touch the hot wire and the ground both at the same time they will get a shock but generally they don't. The adults get a shock when they peck at grass growing in the electric netting and their beaks, combs, or wattles touch a hot wire. They jump back, squawk. and go about their business. They do learn to not peck at that grass so maybe yours have learned to duck down and go under the hot wire.
An acre probably means about 800 feet of fencing. Your best solution may be to put wire mesh around the bottom of the fence to stop them from going under that bottom hot wire but that's a lot of fence. With goats I don't think I'd try plastic netting.
Yeah, I was overthinking the rain thing. I have experienced dead leaves and trash building up against the netting and shorting it out. Sometimes it is wind but the worst is when I get a heavy rain and water causes that. I use a rake to clear it.
