I have a run attached to my coop that is sitting out in the direct sun. I have a tarp over half the top to provide them with some shade. I was thinking about some type of a bush to plant inside the coop to give them some extra shade or maybe something to plant outside the run and will run or climb up and I can train it to cover the top. The top of the run is covered with wire fencing material, so was thinking maybe a grape or some other type of running plant. Maybe a fruit that will also provide a snack for the chickens. Any ideas?? Thanks!
