This is from my game cam over the holidays. The girls are locked in the coop so they are safe. The run has double layers of hardware cloth on the sides and one layer is buried 12 inches in the soil with a concrete footing. The top where the bob cat is walking is plastic roofing. They seem pretty safe at 3am but it may be a problem if he comes back during daylight hours as the rest of the roof is plastic mesh to keep raptors out off the run. The bobcat could probably claw their way through the mesh roofing in the run. never a dull moment.
