I should mention, we have a couple dogs that are not chicken safe so the entire run is enclosed in welded wire and then a layer of chicken wire is run around the inside to keep their little heads inside the run so that a weed does not entice them into the danger zone and that is then curved down and buried to deter diggers into the run. The exposed top is all covered in welded wire to keep any predators out since my dogs are inside sleepers. The wood you see is pallets to hold the compost bins that they get to dig through and deposit nitrogen to help it along. I am pretty proud can you tell lol?
