We used the Gallagher fencing.

This was before we had chickens but had/have an escape artist for a dog. She would dig herself out no matter what we did to the bottom of the fence. It did not help that the folks at the golf course would give her the last bite of their hotdogs. The golfers kept doggie biscuits in their bags to feed to strays. When I finally convinced the to stop feeding the dog, they would let her into the club house to eat the peanuts and pretzels off of the bar floor. She was like the veloceraptor in Jurassic Park (Clever Girl). We finally ran a wire ~8 to 10" off of the ground. The electric fence finally worked. You just have to flip a switch to cut it off and it runs off of D batteries. It also keeps our other dog, who hates the little, ill-mannered, rat dogs next door, from digging through the solid wood fence.
