Bglenut, what I was thinking was a pen that was large enough to raise wild rabbits with a way to drive them into a smaller catch pen on one end when I needed to remove some of them. I would not want walking lanes except around the edge of the pen. Instead of building it in a square I considered a rectangle shape making it much longer than wide to help in a rabbit round up. Something like 50' X 300' = 15,000 SF which would be a little over 1/4 acre. Do you have any suggestions or do you still think this will work?
