Hey folks, quick question for you. I recently converted a portion of my garden into a chicken run. I'm about to plant in the remaining garden space but am now left wondering if there are any concerns having the run right beside the garden as far as possible contamination goes. I suppose I could put in a buffer zone of pretty flowers between the run and my veggies if I had to. If such a buffer zone is advisable, how wide should it be? The coop and garden are in a raised bed, the garden is on the right hand side. the run and garden are separated by stacked ties (same as rest of bed is constructed from). I have 5 chickens, so it's not like a major farm operation going on. Thanks in advance for any advice you can share!
