OK, We are nearly done building our first chicken coop so this is a log ways off, but I hope in a couple years time, to make our land fairly self sufficient. And I am a planner so I think about stuff like this daily... Jot down notes, sketch plans on graph paper, etc. What I want to know is how much square footage can be cleared per chicken per season? I want to build a fence enclosed multi plot garden with an attached coop so that we can release the chickens into different "runs" during different seasons, effectively letting them clear the ground as much as possible all the while fertilizing as they go. So when we move them into the next run, we are nearly ready to plant with minimal work in the previous plot. Just trying to figure out the math so I can figure out my specs per how many birds we want. Does anyone have any experience?
