What would you do?
That's a huge plot! I would be curious what the topography is like. If this were me, I'd be thinking about two things:
1) What sized
chicken tractor / animal pen do I want to design for? The plot looks prime for rotating animals around in a circle, maybe building a flat road (pasture) for their primary
shelter to travel along. Ridgedale
Permaculture has some great examples of designing their landscape for animal rotation efficiency. Work from that base and design tree & earthworks projects around that base. Even if there aren't any animals, having a nice wide track for tractors. / wheelbarrows is always nice.
2) How can I cut this fencing project short and build some next year?
