Iv built a large chicken tractor, 12' x 6'. Is bottom netting requiered for a chicken tractor?

I don't think you want to use a bottom netting on a tractor, but you might want to consider using a "skirt" of maybe 18-24 inches that goes out from the sides to deter critters from digging under the tractor.
