Colony Raising Free Range Tractor Rabbits

I live on a 600 acre organic hill lamb, hogget and mutton farm in Wales and am looking at getting some meat rabbits. I plan on raising them in a colony tractor. The tractor is going to be triangular prism shaped and have wire on all sides and the floor to prevent burrowing and escaping as most of our ground is uneven. My question is, is it okay to use the same wire for the sides as the floor? I am going to use galvanised wire mesh (not chicken wire) and the spacing is going to be about 1" sq. to prevent the baby's escaping as I heard any larger and they will just walk out. Will the wire crush the grass stopping the rabbits from eating it? And will it hurt their feet even if it is flush to the ground?

What stocking rate of rabbits are you doing?
I believe half inch is kinder on feet if it will be off the ground at any point but if you're having it flat on the ground then actually I'd say the bigger the gaps the better for the floor...if they all have enough room to stand on a board or in a shelter with a solid bottom while you move the tractor. Otherwise broken bunny feet can occur.
The bigger the opening the better the forage can poke up through the gaps so they can mow it down rather than pull at the bent over bits, uprooting many blades. If you ran them on grass pre grazed by your other livestock that could work with smaller gaps on the floor.
