What I hadn't realized is that they can use the hardware cloth to climb - I can see its muddy footprints on the wire all the way up to the roof! I need to understand how an electric wire will work and not electrocute me. Also whether plugged in or solar with battery. I think I have to sink a ground rod. It is all a bit intimidating!They are really nasty. They will reach those little hands through the wire and pull the chicken to them if they can. That's another reason for hardware cloth. Hands don't fit through.
