I've purchased a coop/run online to start with 4 chickens but would like for them to have a bigger place to play while we are home. I've been comparing making a PVC v/c wood structure online here then a co-worker suggested using my trees as a post for a natural looking run. The run will be going in the wooded area behind my house where I have a ton of trees, mostly skinny pine ones. I have a flatter area with around 20ft x 20ft between the trees. I know chicken wire is a no-no and all the hardware cloth I'm finding is 36" or 48". We have dogs, cats, squirrels, hawks, snakes, deer, and wild turkeys that have been seen in my woods so I want to make them safe from predators. I've never built anything from scratch so I don't get how to connect the heights of cloth without using a 2x4? Would I use 2x4s to make a base around the trees then fold the hardware cloth back and put rocks on it? How do you attach the hardware cloth to the trees? If anyone has done this and has pictures, I would appreciate posting them. Thanks!
