If the floor of the coop was covered in 1" hardware cloth the bird droppings would fall to the ground but snakes and weasels predators can fit in a 1" hole . By using 1/2" hardware cloth you can keep snakes and weasels out but the droppings won't fall thru the holes (making it harder to clean)If you use hardware cloth on the floor of the tractor the chickens can only eat grass thru the mesh holes.I was also thinking of using wire across the bottom to prevent predators from coming up under where it sits.
