The last post on the bucks omitted a lot of the little details about the pen that we just made up on the fly, but that might be helpful for someone looking to build a pen. Before we started frequenting the Co-Op and Tractor Supply I never knew most of the stuff we use everyday even existed. I hope that by sharing the details other readers who are interested in the little stuff can get a better idea of exactly how it's all put together. I'd also love to hear feedback and what other people have done that worked well for them.
As you can see in the photos above and below, we put an electric wire around the top of the cattle panel using 2" insulator attachments that we got from Tractor Supply. The purpose having it stick 2" inward is so when the bucks climb on the fence they get zapped on the head and learn not to do that. If they are allowed to climb the fence will slowly lean over and they'll be able to climb out (and it will look ridiculous). At each gate there is a gate handle so we don't have to duck under the wire if we don't want to or if we need to bring something into the pen.
