When I was a kid, we had a pet rabbit that lived in the large chicken pen and coop we had. Once in awhile he would dig out and go to the neighbors to eat their lawn. We fixed that by laying wire cloth on the ground in the pen and covering with dirt. I have been admiring all the nice rabbit set-ups you all have been building and got to thinking about whether we could raise rabbits without traditional rabbit cages. If we could make the pen predator proof and could keep the rabbits from digging out, what would be the reason NOT to raise them cage free?
