I am looking for suggestions for a large movable coop. Not quite like the tiny chicken tractors meant to be moved daily, I'm thinking of a coop on wheels that could be moved once every couple of weeks to cycle chickens around my 10 acre property. The run would be separate and quite large. Has anyone tried something similar to the "ChickShaw" design from Abundant Permaculture? I have some concerns about its durability and open concept, but the design and lightweight PVC panel siding seems interesting. I am planning for my first ever chicks, and would love some expert guidance here. I am in zone 6 Indiana.
