In our neighborhood, we need to "properly screen" our run so that it is not offensive to the neighbors. I selected some beautiful azaleas and was about to put them in, when I discovered they are toxic. We decided to put in boxwood, which the landscape nursery did not have... but that is supposedly poisonous, too. Then I traded my azaleas for English Laurel. The lady at the nursery thought I was nuts. I brought them home, and guess what? They are on the toxic list. Seems like every plant under the sun is on the toxic list. So what do I plant as hedging around the run? Someone else posted that they have laurel and her birds roost in it. Am I being silly? I do have the concern that they will pick at the plant through the wire run because there is nothing green in the coop and you know chickens must investigate everything. I had also planned to build a planter for an almond tree and a dwarf cherry, which, surprise! Are toxic, too. Any thoughts?
