I started the build today! I plan to use pallets on both ends. I will drive t posts in on both sides and run welded wire along them. The roof arch will be made of 4 cattle panels. I am planning to use some metal roofing for part of the roof so the birds don't get rained on. The rest will be covered in finer wire so varmints can't get in. I want to make the roof high so the guineas will be more likely to roost there.PLEASE tag me when you do. I'd like to see a coop build from cattle panels.
