I tried searching for this, but my searching skills may be lacking. My run is chain link dog panels, with chick wire on the inside to keep the chicks from sticking their heads out. Unfortanetly they don't have any shade until later in the evening though. I know they would spend more time outside if they had shade. So I'm wondering what I could plant bush wise. Would lilac, forcynthia, climbing roses, and/or flowering quince be ok? Those I already have here, so wouldn't be a problem to transplant some there. Otherwise I will need to go buy some. Are they poisonous, or would they work for adding shade?
