My daughter received 6 chicks for her birthday. We've got about three weeks until we are going to need to move them outside. I'm thinking a tractor is the ideal way to go. We have plenty of land (12 acres), but LOTS of predators including weasels. I want the very best Fort Knox of chicken tractors. I don't care what it cost. I will pay anything to not have these chicken killed. I've called around to coop builders in my state and they either can't get it done in 3 weeks or don't build tractors, only coops. Does anyone have recommendations for a good tractor I can buy online. I have been looking at this one from ChickenCondos.com, but it doesn't appear to be weasel proof.
