The main problem I ran into when trying to have plants in, or surrounding a run is not just that the chickens pluck, peck at, or scratch to death anything that is green, but also that their poo burned the heck out of whatever was trying to grow there. Even if I did get something to grow around the run somewhere, the soil became so harsh, that the leaves would turn yellow and the plant died off rather quickly. I once had a couple of huge potted plants around the outside of the corners of the run. Those weren't in the ground, so the soil was unsullied by poo and those plants did just fine. Whatever managed to grow in through the wires made the chickens happy too.
