We'll have three storage sheds that will be converted for animals. Only on needs some heavy repair thanks to a leak my FIL has allowed to continue for years and a stubborn groundhog that tore up the wooden floor. The other two were built for my MIL so he took more time building them and gave them concrete floors.
My FIL is a bit of a hoarder when it comes to wood, tools and car parts. When we were working on my chicken coop he kept showing up with more plywood and 2x4s. He probably has almost everything we need.
