I just moved to Middle Tennessee from Florida. I brought a 6 year old Buff Orpington and 2 year old Golden Wyandotte with me. I would like to get more chickens. I would like to build a chicken tractor for about 6-10 chickens. I am looking for well written plans for the tractor. I raised 6 chickens in Florida. I have 15 acres here. I want to make sure my chicken tractor is totally predator proof and protects the chickens from the cold and the heat. I am also looking for ease of maintenance. I will probably use some kind of movable run, using electric wire. I am considering a goose to keep aerial predators away.
