Chicken newbie here! I am planning to build a semi-stealth chicken tractor in MO for 3 girls. I live in the suburbs but have seen hawks, raccoons, skunks, opossums, and fox in the immediate vicinity. I need my tractor to be easily moveable by two adults and it will be my girls primary home. They will be out a few hours a day when I can watch them. I want to put a floor on the tractor to discourage predators (and because it seems much easier than the wire skirt idea) but I want my chicks to be able to scratch around the lawn and munch on grass and bugs. Has anyone successfully done this? What size wire fencing/hardware cloth did you use? I am looking at a 3"x 2" opening for the floor only (please note, I will be using 1/4" opening galvanized wire for the sides.....) Do any of you think that will work (and keep out the coons/foxes?) If not, any other suggestions? Thanks in advance!
