Maybe. The 'slaughterbots' of the future as depicted use explosives to blow holes in buildings. I'd imagine they could arrange multiple in a circle to blow an arbitrarily large hole in fencing or netting. Also, usually chicken-wire fences just go around what's being protected, not necessarily over it (except for small farm animal enclosures, like actual chicken coops). It's hard for me to imagine entire buildings / neighborhoods / cities with chicken wire covering over the tops of the buildings in a way that couldn't be quickly breached with explosives. Or drones could unroll detcord in a circle against the fence as well.
