So I'm building my first chicken tractor. I'm making it so that the 4 sides are bolted together for easy assembly, disassembly, and storage. The only piece to the puzzle that has me scratching my head is the roof. My mind has been going nuts. I'm on a bit of a budget so I used 1x3's. I'm trying to figure out how to make a roof just at the back end for shelter that A) is lightweight enough that it won't warp the 1x3's too badly, B) will protect the hens and give them shelter. And C) will be able to come apart when I look to disasemble. Any and all suggestions are welcome.
