So I was thinking about using these really cool pallets that I got that have plywood already attached to them they are about 2 ft wide all sides. My question is if I put two together that would make it about 4 feet long 2 ft wide then I would make an external nest box for the coop. Then I can make it pretty much as high as I want I was thinking 4-5ft tall for the roosting bars. How many chickens do you think I could fit in there if they're just sleeping. They would have a huge run and yard area.
