I am sick and tired of trespasing pets and wild predators! Some of my beautiful chocins had to sacrafice their tiny lives to predators and pets, and this won't be going on any more! My dad had a great idea! He spun electrical wires around the coop and chicken run( on the outside of the fence) just so that the chickens can't reach the wires. We tested the electrical wires on our dogs(who normaly liked a little chicken dinner). The wires carried 20 000 volts( just enough to scare of predators, not kill them). Our dogs got a little shock when they tried to break trough the wires! They never tried it agen! So try this method(it's a 100% fail proof method)! And if you are realy interested in electronics check out my dad's webpage(www.jdm-electronics.com)wich has alot of information on electronical stuff( my dad's hobby), a page on aeroplanes( my dad's other hobby and my uncle Danie's work+hobby), a page on our weather and, of coarse, my page on chickens! So PLEASE check out our webpage ( www.jdm-electronics.com), even if it's only for the chicken or aeroplane part! Annette.
