Anyone ever built a tractor/coop out of a old trampoline frame? There was one here when I moved in and.. well, it is still here. I keep looking at it and thinking I could turn it into one. My two adult chickens are free range and been like that since they showed up. (long story ) However, I have two chicks (one of their offspring and a silkie) and do not want to free range them. If anyone has.. please share pictures.
