For multiple reasons, I built raised planters all around my coop and run. The inside of the planters is about 12" wide and they range in height from 6-12". My wife wanted to plant vegetables there but our chickens free range from dusk to dark, so that didn't work out. Do any of you have some ideas? I'm considering ornamental grasses or sunflowers. I'm not sure sunflower roots could spread out enough though.
