Right now we have a substantial coop. DH built it from scratch and it looks like a commercial built tool shed. We just tore down the run - DH called it the ghetto run. And he attached a small rectangle run for now. We also have a "tractor" DH built that is quite the posh thing! Very small, meant for only few transitioning chicks it started out being a "tractor" and ended up being SO heavy it can only be moved with a tractor! It isn't what I wanted really. I am planning to build a bamboo and chicken wire tractor. Only a long rectangle with a tarp over one end. So here is my question: Do any of you use both a coop and a tractor?? Like, have a coop and permanent run but sometimes put the birds into a tractor for the day ?? We have a serious predator problem so the flimsy tractor that I can move myself will not hold up for overnight protection. Ideas??? edited to add: We have 14 adult birds, five teens not yet laying, and a mama and 4 babies in a brooder in the garage.!
