I'm thinking about building one like the PVC tractor in the coop photos. I'd like to keep separate flocks if we decide to get more sooner, I don't know though...my 3 girls get along so well, no noticeable pecking order to speak of, I'm afraid a larger flock would cause "issues" we don't have right now. And I want a Sebastopol goose...talk about ticking off the neighbors, lol.
