I have the ElectroStop style from Premier that has the bottom wire as the ground wire, making it easier to move from place to place. The downside? It is sheep fencing, so the squares will not contain my meaties and most of them range out of the fence all day. It is an excellent fence and will come in handy for full grown DP hens later on but for the meaties, it is more of a hope than a solution. I only hope they can make it back to the fence before a ranging dog wipes out the flock.
I also have a dog watching them but he is too friendly to stray dogs, though he keeps out everything else that may prey on them. My CX are 4.5 wks old and I have had no losses to preds though they range all over 2-3 acres of land and into the nearby woods.
I got 164 ft. of fence, with posts built in, for $164 and that is with the shipping included. It has a very powerful bite to the fence and seems to be an excellent dog deterrent and will even keep some of the less adventurous CX inside...but not many while they are still small enough to take a running jump through that bottom square.
